Co2 Optical mirror of bystronic
The output laser wavelength of carbon dioxide laser is determined by the output mirror on the laser. The inner side of the laser output mirror is coated with an optical film layer. When the initial stage of the laser is opened, a variety of wavelengths of laser will be generated in the laser resonator, which will be directed at the optical film layer of the laser output mirror. For example, the existing laser output mirror generally has a higher reflectance for 10.6μm wavelength laser. In the initial stage of laser opening, more 10.6μm wavelength laser will be reflected back to the laser resonator. According to the principle of laser generation, the reflected 10.6μm wavelength laser will excite the laser medium to produce more 10.6μm wavelength laser in the resonator. When the laser power of 10.6μm wavelength reaches a certain level, the laser beam will break through the output resonator of the optical film layer on the laser output mirror to realize the vibration and output of 10.6μm wavelength laser. Due to the long wavelength of 10.6μm laser, there will be some shortcomings such as blurred writing and large laser loss when used for laser marking and laser engraving.
