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!
