CO2 laser material for the CO2 laser working mixture of gases, the main applications of the laser wavelength of 10.6μm. Since this type of laser for laser conversion efficiency high, while the heat generated by the laser work can be spread rapidly by convection or delivered to the laser gain region, the average power output of the laser can be a very high level, to meet the high-power laser processing requirements. Home and abroad for high-power C O2 laser processing lasers, mainly cross-flow, axial flow lasers. Cross-flow laser beam quality is not good for multi-mode output, mainly used for welding and heat treatment; axial laser beam quality is better, the base for the fundamental mode or quasi-mode output, mainly for laser cutting and welding. As the CO2 and Nd: YAG laser with a huge power output, through the cumulative effect of making a large number of thermal energy deposited in the irradiation causes the material to melting, evaporation, to remove. To improve the laser beam divergence, it is necessary to use model selection techniques for laser resonator oscillation mode select, filter noise form the base model (TEM00) output. Selected mode of the method are more holes in which the use of aperture method for reducing the divergence of the laser beam is both simple and effective way, the hole diaphragm hole radius r0 is selected as the place of the laser beam at an effective aperture section radius w (z), it can enable the fundamental mode beam passed, while the higher-order transverse mode beam suppression.The supply management of green laser pointer is important to the market of green laser pointer .
However, the same laser output power, pulse width the same, only adjust the pulse frequency, the change in peak power per pulse. As the pulse repetition rate increases, the hole depth values are getting smaller.

Displacement type optical attenuator is based on this principle, intends to allow optical fiber in the dock, the occurrence of a certain dislocation. Loss of light energy, so as to achieve the purpose of controlling attenuation, the displacement type optical attenuator is divided into two kinds: horizontal displacement type optical attenuator, the axial displacement type optical attenuator. The lateral displacement type optical attenuator is a more traditional method, the magnitude of the transverse displacement parameters in the micron level, it is generally not used to produce variable attenuator is only used in the production of a fixed attenuator, and welding or stick connection, there are still a large market, the advantage of high return loss, is generally greater than 60dB. laser pointer is the professional assistants for teaching and lecturing with PPTs.
Two fiber axial displacement type optical attenuator on the process design as long as the machinery to a certain distance for the purpose of attenuation, can be achieved. This principle is mainly used for the production of fixed optical attenuator, and some small variable optical attenuator. The film-type optical attenuator. This attenuator is made of light reflected light in the metal film surface, the principle of film thickness. If the thickness of the metal film deposited on glass substrate is fixed, it is made of a fixed optical attenuator. If oblique inserted in the fiber deposition have different thickness of a disc-type metal thin wax glass substrate, so that the thin film of different thickness of metal inserted in the optical path, you can change the intensity of the reflected light, you can get different attenuation volume, made of the variable attenuator. For different line interface, you can use a variety of fixed attenuators; If the interface is a pigtail, available pigtail type optical attenuator is welded to the optical path between the two fiber; connector system debugging process interface converter or converter-mounted attenuator. It is the uninterrupted wireless RF technology of laser pointer .
In practical applications often need optical attenuator attenuation amount can be changed with user needs. Therefore, the variable attenuator, a broader range of applications. EDFA, CATV optical system design margin of the actual system of the optical power margin is not exactly the same, for example, the system BER assessment to prevent receiver saturation, it must be inserted in the system variable optical attenuator, the other in the fiber optics (such as optical power meter or OTDR) measurement, calibration will also be using the variable attenuator.

However, the calculation of the duty cycle is calculated, so the positive logic PWM logic of the procedure will reverse once. AD sampling interrupt is generated by the DSP hardware, after the When DSP completion of one AD sample, will produce an AD sampling interrupt. The program responds to the interruption, into the AD sample the ISR. In the AD sample IR, made 12 AD sample value. Sampled values into digital controller program to calculate the PWM duty cycle of the next cycle, and then update EVA_TIMER1 compare register. Finally reset the AD converter to complete the interrupt acknowledge []. Digital controller design is the difficulty of the entire software system. The controller is good or bad, is directly related to overall system performance. The customer can use the green laser beam of laser pointer to observe or show the star.
Digital controller design the most difficult is precisely the transfer function. First in a changing input voltage; Second, the internal resistance of the load is non-linear changes; Finally, the output filter inductor inductance decreases with increasing current. By the relationship between current and inductance, ferrite core 10A in the inductance decreased by 20%. Inductance change, a direct impact on the system transfer function.
Krypton lamp dynamic impedance R = 3Ω about. As a result of the average current control method, the actual control is the average inductor current. Inductor current and duty cycle of the transfer function onto the process is as follows, using state space averaging method to establish a system of small-signal model, and its strike Laplace's transform. The whole system open loop transfer function: The above analysis assumes that the system is a continuous system, while the actual system is a discrete sampling system, need to take into account the sample and hold time and control delay time. Sample and hold time the main aspects of the decision of the AD converter link and PWM output to control the delay time is determined by the software architecture adopted.

First, the history of quantum amplification in the microwave band (1953), 1954 - CH Townes, IP Gorden, HJ Zeiger achieved using NH3 molecular beam Maser grow to more short hair - ammonia beam maser, 1958- AL Schawlow, CH Townes, AM PoxopoB Maser principle extended to the proposed light band - laser, 1960 - TH Maiman of Bell Lab Ruby for the first time laser l = 6943? red (early name: les, quantum oscillator, lasing light device by the laser, "Laser" - Qian put forward in 1963 61 years of China (Asia), the first laser was born in Changchun (Changchun Institute of Optics and optical machines College), by Wang Jiang Yuanshi invention. Cavity light field can be calculated by Kirchhoff diffraction by the mirror M1 on the field distribution in the cavity caused by the wave obtained. Optical cavity is the cavity field is propagating along a traveling wave through the mirror part. Wave function is multiplied by the specular transmittance t. As already described begin to speak of the physical model concept, the first review since the integral equation model to reproduce the physical meaning of the concept of the establishment of the laser mode. Re-formed and began to solve the self-reproduction of symmetric integral equation model to understand the specific output of the laser field distribution. Green ray laser pointer are the most competitive products.This section discusses the use of Q-width of the laser pulse compression techniques for high-power pulse method. In order to be more narrow pulse, mode-locking can also use special technology to laser beam modulation, the beam in different vertical oscillation of the mold has a definite phase relationship, so that the coherent superposition of each model ultrashort pulse. Mode-locked laser pulse width of up to 10-11 ~ 10-14s, the corresponding high peak power. This section also works as a mode-locked laser brief. The basic principle of Q-switched laser: a way through to the cavity loss value changes in accordance with the prescribed procedures, thus reducing the optical pulse width, peak power output greatly increased. This kind of laser pointer can be used as a commanding pen.Q-basic process: beginning at the pump, so that the cavity loss increases, Q values decrease, then the device becomes higher oscillation threshold, the oscillation can not be formed, on the level density inversion may have accumulated a large number of When accumulated to a maximum value (saturation value), the sudden loss of the smaller cavity, Q sudden increase in value, when the device suddenly goes low oscillation threshold, the rapid establishment of the laser oscillation, the same cavity as a very high avalanche establish a strong oscillation speed in a short time a large number of inversion is consumed, the light energy into a cavity, while the output of a strong laser pulse. Mode-locked laser is a further special modulation.

Output of the laser light, the wavelength distribution is very narrow, so very pure color. The output of red helium-neon laser, for example, the wavelength of the light distribution can be narrow to 2 × 10 ^ -9 nm krypton lamp emits a red light wavelength distribution of the two ten thousandths. Thus, the laser is far more than any kind of monochromatic monochromatic light source. In addition, there are other characteristics of the laser: coherent and good. Laser frequency, vibration direction, phase high degree of consistency, the laser light waves overlap in space, the overlap of light intensity distribution of the strength and stability will be white phenomenon. The company has the high professional requirements for the worker of laser pointer .
What is called "stimulated emission"? It is based on the great scientist Albert Einstein in 1916 proposed a new set of theories. The theory is that the atoms in the composition of the material, there are different number of particles (electrons) in different energy levels, in the energy level of the particles by a photon excitation, jump from the high energy level (transition) to a low level, then it will radiate light and excitation light of the same nature, and in certain conditions, can stimulate the emergence of a low-light glare of a phenomenon. This is called "light amplification by stimulated emission of radiation", referred to the laser. There are four main characteristics of the laser: laser high brightness, high directivity, high color and high coherence. The laser has been widely applied to the laser welding, laser cutting, laser drilling (including the slant-hole, different holes, plaster hole, perforated tipping paper, perforated steel, perforated packaging and printing, etc.). laser pointer can be customized in the specific supplier.
Laser hardening, laser heat treatment, laser marking, glass engraving, laser dermabrasion, laser lithography, laser system, film, laser film processing, laser packages, laser repair circuits, wiring of laser technology, laser cleaning. After 30 years of development, the laser is now almost ubiquitous, it has been used in life, all aspects of research: Laser acupuncture, laser cutting, laser cutting, laser welding, laser hardening, laser discs, laser range finder, laser gyro instrument, vertical laser, the laser scalpel, laser bombs, laser radar, laser guns, laser guns, in the near future, the laser will certainly be more widely used. The specific technician of laser pointer is very professional.
Interviewed Professor Cai Guoling, Professor Cai Guoling replied: "No surgery is not an absolute one hundred percent secure, even if the correction as Lasik surgery, already have very high security, and accuracy, there are inevitably has its dangers, but since the new vision of Quanzhou Eye Hospital to build hospital for treatment of myopia has nearly 40,000 cases of myopia surgery success stories record: never in one case of blindness caused by the example of serious complications is 0!

The basic optical system optical head and optical parts

The brightness of green ray laser pointer is really much higher compared with the yellow ray laser pointer .
The basic optical system optical head and optical parts of the income poor. DVD optical head is the most critical components of the system, its basic principle is as follows. Optical head is 1 rem lens, 2 collimating lens, 3. Polarizing prism, 4 prism, 5 mirrors, 6.1 / 4 wave plate, 7 focus error detection optical system and 8. Seek error detection optical system and other optical parts and optical systems, 9 focus control servo (F-ACT), 10. Seek control servo (T-ACT) and other servo-mechanical control parts, as well as semiconductor laser diodes, multi-split photodiode PD (photo diode) and other optical components consisting of.
General multi-mode LD RIN way lower, but the anti-reflective optical interference, without superimposed high-frequency drive current for the single mode light-emitting LD, a strong impact on the optical signal reflected light must be superimposed on the drive current frequency, generally about 500 ─ ─ 700MHZ range. LD to exert internal energy of incident light to maintain a certain, usually containing the photodiode PD, do APC (auto power control) with. Because DVD uses a laser wave length, so the light surface aberration demanding, so try to use the LD light in the middle part of that wave-front portion of income difference is small, but also consider the energy use efficiency. laser pointer works with 1 AAA battery.
So that with a regular CD with a different head. Need plastic prism, it is the role of the flat oval-shaped light, transformed into a circle parallel light (pictured), the role of polarizing prism. Is the light emitted from the LD of the reflected light from a separate CD, so that the first reflected light does not return to the laser cavity LD, resorted to shooting the laser does not produce noise, the second is that the reflected laser reflection with information beam can have a minimal loss, the first surface of the filter Q of P A linear polarized incident light than the ingredient, making it a pure linear polarization P, Q must also face the whole P linear polarizer Through, S linear polarized total reflection. Wavelength of laser pointer is 532nm.
The design of the lens material, must depend on the thickness of the disc, if the thickness of the disc does not match with the design values, will produce spherical aberration, the aggregation properties deteriorate, which is why for a DVD disc with 0.6mm thick of things 1.2mm thick lens can not read CD-ROM The CD-ROM signal grounds. General read-only type with less power, use of non-spherical optical resin can be injection, but with the power of a larger record type, generally with multiple sets of optical glass lens combination, the ministries of the imaging system aberration goods must be strictly controlled .

Power density of laser processing is the most critical parameters

Power density of laser processing is the most critical parameters. The higher power density, in the microsecond time range, the surface can be heated to the boiling point, resulting in a large number of vaporization. laser pointer has its specific features.
Therefore, high power density for the material removal process, such as drilling, cutting, carving favorable. For lower power density, the surface temperature reaches the boiling point to go through a few milliseconds, before vaporization at the surface, the bottom to the melting point, easy to melt to form a good solder. Therefore, the conduction laser welding, the power density in the range of 104 ~ 106W/CM2. Laser pulse shape in laser welding is an important issue, especially for welding thin is more important. When high-intensity laser beam shot to the surface, the metal surface will be 60 ~ 98% of the laser energy reflection is lost, and the reflectivity change with surface temperature. laser pointer is also called mini-laser pointers.
In a laser pulse period, the volatility of the metal reflectivity. Pulse width is one of the important parameters of laser welding, it is both material removal and material different from the melting of the important parameters, determining the cost of processing equipment and the volume of key parameters. Defocus amount of the welding quality. Laser welding usually requires a certain issue from one focus of the laser power density at the center spot is too high, to evaporate into the hole. Leave the laser focus of the plane, the power density distribution is relatively uniform. Defocus in two ways: positive and negative defocus defocus. Focal plane at the top of the workpiece is out of focus, and vice versa for negative defocus. laser pointer is the best sellers among the same series of products.
Geometrical optics theory, when the issue from an equal positive and negative, corresponding to approximately the same power density on the plane, but in fact obtained pool of different shapes. Negative defocus, the availability of greater penetration, which is the formation of the pool. Experiments show that the laser heating 50 ~ 200us material begins to melt, the formation of liquid metal and the emergence of sub-vaporization asked to form a city-pressure steam, and high speed jet, a dazzling white light. At the same time, high concentrations of vapor to liquid metal movement to the pool edge, the formation of sag in the center pool. When the negative defocus, the material internal surface area is higher power density, easy to form a stronger melting, vaporization, so that light passes to the deeper material. So in practice, when required penetration depth is large, the use of negative defocus; welding thin materials, it is appropriate is out of focus. laser pointer gains in a lot of popularity.

Different wavelengths of laser eye injury site, the wavelength partition wavelength range (nm) primary site of injury, 180-400 UV laser cornea, lens, visible laser 400-700 retina, choroid, near-infrared laser 700-1400 retina, choroid, lens, in Far-infrared laser 1400-106 cornea, the laser operating environment in the long-term workers in the eyes by long-term effects. In operation and use of lasers, even if not directly by the laser irradiation, resulting in injury accidents. However, the anti-out laser rays through walls or other objects produced by micro-reflections, long-term work in this environment of people, a high incidence of cataracts. Prolonged exposure to green laser light, especially when the laser pointer over 5 mW of power, just a few seconds may cause functional vision of the human eye damage.In fact, in addition to laser speckle, the majority of patients with traditional Chinese medicine freckle is now widely used means of a freckle, Vea beauty spot capsule beautiful community is the quality of supervision by the State Food and Drug approved by the Board of pure herbal products, is the speckle industry Jiao Johnson were. When we create a condition, such as the use of appropriate media, cavity, enough external electric field is amplified by stimulated emission of radiation to be more than the stimulated absorption, so overall, there will be photon emission, resulting in the laser.
YAG laser at the receiving probe laser beam emitted when the laser beam energy should be about 4%, that is out of the laser perforation at the receiver with a frosted glass, frosted glass on from the 15-20 point range to reflect the probe, If you do a free pulse waveform, the probe attenuation to add one to three layers of paper; if it is Q-wave, the attenuation of the probe front of the paper than do the more free pulse. When the measured waveforms are done, do not forget to switch off the probe. Ordinary light is light in all directions. Make the emission of light propagation in one direction, you need to light a certain condenser fitted with devices such as car headlights, and searchlights were installed on the role of the condenser mirror, so that radiation is to bring together in one direction injection. Laser emission of the laser, born in one direction injection, beam divergence is extremely small, only about 0.001 radians, nearly parallel. In 1962, the first human use of laser irradiation the moon, the moon's distance from the Earth about 38 million km, but the laser spot at the lunar surface less than two kilometers. If condenser works well, seemingly parallel light beam searchlight shooting the moon, according to its spot diameter will cover the entire moon. The laser pointer company manages to attract more customers with the low cost and expense.

This kind of laser pointer has the higher expense

The low cost of laser pointer can bring more profits to the manufacturer.
Deep penetration of laser generally used continuous wave CO2 laser, these lasers can maintain a sufficiently high output power, resulting in "holes" effect, penetration throughout the workpiece cross-section to form a tough welded joints. The laser itself, it can produce just as a heat source, a good parallel to the beam direction of the device. If it is oriented and effective treatment of the workpiece after the shooting, the input power to a strong compatibility, so that it can better adapt to the automation process. In order to effectively implement welding, laser and other necessary optical, mechanical and control components together to form a large welding system. This kind of laser pointer has the higher expense.
The system consists of laser, beam delivery components, the workpiece handling and mobile devices, as well as control devices. This system can be only manually by the operator simply moving and fixed parts, including parts can also be automatically loaded, unloaded, fixed, welding, inspection. The system design and implementation of the total requirement is to secure a satisfactory weld quality and high productivity. In general, the good effect of laser welding carbon steel, the welding quality depends on the impurity content. The same as other welding processes, sulfur and phosphorus are the welding crack sensitive factors. The expected use time of laser pointer can be really long.
In order to obtain a satisfactory weld quality, carbon content exceeds 0.25% needs to warm up. When different carbon steel welded with each other, the welding torch can be a little biased towards low-carbon material side, to ensure joint quality. Low-carbon rimmed steel as sulfur and phosphorus content, not suitable for laser welding. Low-carbon killed steel due to low impurity content, welding results are good. Medium and high carbon steel and ordinary steel can be a good laser welding, but need to preheat and post weld treatment to eliminate stress, to avoid crack formation. Under normal circumstances, the laser welding of stainless steel welded more easily accessible than conventional high-quality connectors. Due to the high welding speed is very small heat affected zone, sensitization does not become an important issue. Compared with carbon steel, stainless steel, low thermal conductivity coefficient is easier to get deep penetration narrow weld. The actual use time of laser pointer can be longer than expected if laser pointer is used properly.

With laser technology of Q-1968, the time resolution has been increased to nanosecond order of magnitude; In addition to the absorption spectra can also study of its fluorescence spectrum. Clamping technology development in recent years, the time resolution has been further improved and reached picosecond and sub-picosecond. Therefore, this laser flash spectroscopy, often referred to picosecond spectroscopy or sub-picosecond spectroscopy. Of course, the experimental study of the fast process, in addition to the laser light source of ultrashort pulse (10-12-10-13 seconds), but also must have the appropriate testing techniques. The member card of laser pointer website can be used by others.
At present, the experimental study of the fast process, usually to take such a test, the laser pulse with a beam splitter is decomposed into two beams of light, which a bunch of strong pulse to motivate the study material fast, while with the other beam weak pulse to probe the response under intense pulsed excitation. Figure (10-16) used to measure organic molecules or bio-molecule fluorescence spectroscopy and lifetime of the experimental apparatus. Issued by the mode-locked neodymium glass laser picosecond pulse laser light is divided into two by a beam splitter. All the way through the ADP crystal multiplier lens launched into the sample chamber so that the sample molecules to be inspired. The other way first through the lens make a spark in the pool, resulting in the continuous spectrum. Spark caused by the continuous spectrum of light output after a light ladder, the light is divided into several intervals of the picosecond and a number of beam.

The photoelectric effect was found in 1887 by Hz (HRHertz, 1857 a 1894). The study of the photoelectric effect device is a pumped into a high-vacuum glass balls on the inner surface coated with a photosensitive layer (cathode K), the anode A can be made into a straight line or circular ring. When monochromatic radiation through the quartz window to the cathode K, the escape of electrons from the cathode, e-called photoelectron. If both ends in A, K, coupled with the potential difference U, fly photoelectron in the accelerating electric field under the anode, the formation of the photocurrent in the circuit. The strength of the photocurrent is read by the galvanometer. Like this metal by the irradiation of light and emit electronic phenomenon called the photoelectric effect.

Laser surface treatment of metallic material, is developed over the past decade a new technology. Whether it's black metal or non-ferrous metals, in practice applications it shows a distinct superiority, and in industrial production has been widely used. Laser processing of metal, usually based on a certain mode of the laser beam aimed at the site of the workpiece to be addressed by the workpiece with table movement (rotation or translation) to achieve laser scanning. In order to prevent surface oxidation and the generation of plasma, often using an inert gas protection system, the general handling of the workpiece are air-cooled, some pieces are special requirements can be cooled by liquid nitrogen [14]. As the laser processing show a clear superiority of the quality and effectiveness, its application has been developed rapidly. The safety consideration of Laser Pointer should be included in the instruction of Laser Pointer .
Laser marking and laser materials can be divided into the role of surface marking (such as sculpture) and material conversion (such as bleach). Laser surface marking a method as earlier, it is the use of evaporation or ablation of a shallow surface to produce the desired mark. In recent years, more and more popular in the plastic sub-surface marking. This method usually add some sensitive pigment, laser photochemical change by the increase of plastic or the paint color [15]. The next century, new applications of laser technology will continue to make miracles become ordinary, laser development, history has proven this point. Laser technology will be a better person to be linked with human development, she would quietly serve and not for our lives that we perceive.Vibration method: maintenance, inspection laser printer, a "vibration check" method is very effective. Especially for older or have time for a long time, but no particularly large apparent failure of the printer. Vibration method can be varied, usually the machine or by hand to tap the beat with insulating objects, flick the circuit components, when the fault disappears when you touch a component, which can be visually determine the fault that is here. 
Many laser printer connectors, repair to remember clearly their respective positions, colors, etc., to prevent incorrect insertion when you reset, causing new problems. All wiring must be fixed according to the original position, to prevent cross-sensor electromagnetic field, causing poor print quality. Replacement of the component must be the same type of components, even substitution of components, the main parameters must be consistent, not arbitrary substitution. Laser printers and optical laser components, can not disassemble it to adjust, or will cause the laser aging, focus offset, affect the printing or font-variant. Laser printer cartridge components, can not disassemble it, can not touch the drum, but can not wipe with a solvent free, so as not to damage the photoconductive layer, the cartridge components should be stored on the dark place, avoid excessive exposure caused scrapped.
