The Green Laser Module is composed of laser crystal and nonlinear crystal. In the laser resonator, the LD pump light of 808nm wavelength is used to generate 1064nm laser by the gain of the laser crystal, and then the frequency of the nonlinear crystal is multiplied Can produce 532nm green laser. Green Laser Module is similar to the electronic components in the integrated circuit, with modular, integrated features which can be mass production, reduce costs.
We also can provide IR Laser Illuminator and Red Laser Module,If you are interested in our products,welcome to comtact us
