green laser pointer company adopts brand new imported original binding apparatus
Inadequate: the smallest in the cavity mode, power is not, and the uneven distribution of energy. Applications: laser cutting, punching, applications: laser cutting, drilling, welding, etc. 2, higher order mode, advantages: high output power, a more uniform energy distribution advantages: high output power, less: less: divergence powerful applications: laser hardening , Application: Laser hardening, metal surface treatment 3, uniform optical systems, reflective mirror focus points is to use a large area of broadband high-power green laser led surface cladding and heat treatment of the essential components of broadband, both with excellent light effects.The basic points of Haitong green laser pointer company are: creativity, cooperation, quality and respect. Divergence and alignment system 4, the divergence and intensity distribution, when Z = 0 时, θ = 0 (that is, at the waist, divergence angle of a plane wave) (ie, at the waist, divergence angle is 0? Plane wave) πW02 When Z = when: λ when Z = α when: usually 0 ≤ Z ≤ λ is defined as the beam collimation zone area 1.1.2 of the laser beam brightness light-emitting surface brightness is to describe the characteristics of a physical quantity, light intensity light intensity is described physical properties of a light-emitting surface, light intensity (B) is defined as the solid angle per unit area of the radiation power (P). The creative spirit is the basis for the survival of Haitong green laser pointer company.The light source brightness: solid angle per unit area on the radiated power. The light intensity is: Then: For nearly diffraction limited beam, laser beam focusing properties of a laser beam focus in the form, the transmission type: 2KW less commonly used in laser processing system 1.1.3 Spherical focusing properties of the laser beam reflection: kilowatts or more for high-power laser spherical reflective: kW or more for high-power laser beam focusing properties 1.1.3 2, focal spot size and depth of focus, (1)Haituo green laser pointer firm promotes the spirit of hard struggle. the actual focus lens spherical lens used to focus the laser beam from the smallest spot size can be approximately represented as determined by the diffraction spots waist radius and the minimum determined by the lens aberration diffuse plaques and the minimum spot size radius of which: minimum focus spot size and focal length corresponding to: f = () 3 D 3 1.27λb to get a small focused spot diameter of the wavelength the smaller the better, the lower the better order of transverse modes (b small), the k value is smaller lens (with concave - convex mirror). Focal length and focal spot diameter (2) non-spherical aberration-free lens 2λ f aspheric lens focused spot radius: W '= b πD 2 because: 2λ θ = πD focus on the fundamental mode beam minimum radius: W' = fθ common The minimum laser focus spot size (the smallest commonly used laser focus spot size (f = 2cm)) W '= fθ (3) depth of focus of the important parameters of the laser focus) depth of focus --- Haituo green laser pointer firm keeps in pace with the development of overseas information technology and even has some creativity.Focus on the important parameters of laser A to both sides from the waist to intercept the beam radius increases to 5% at B, the optical axis to reduce the intensity of its points to the laser light intensity at the focus of the half, the distance from point to point as the beam depth of focus λf 2 ? = ± 2 πD D lens for the incident beam on the beam radius can be seen from the above depth and focus the incident laser wavelength and lens focal length proportional to the square, and D is inversely proportional to, so to get a larger depth of focus.
