The United States imported materials  can be used for high power laser.

Material properties:

Zinc selenide material is a kind of yellow transparent polycrystalline material, crystal grain size is about 70 um, pervious to light the range 0.5-15 um. By metalorganic chemical vapor deposition (CVD) method for synthesis of absorbing impurities basic does not exist, the scattering loss is extremely low. Of its light absorption on on the wavelength of 10.6 um is very small, so its the first choice of material for high power (CO2) laser optics .In addition throughout its pervious to light within the band, is also widely used in different optical system of the material.

Zinc selenide material for thermal impact of high bear ability, make it become the best in the system for high power CO2 laser optical material.Its hardness is  two-thirds of multi-spectral ZnS, material is qualitative soft easy to scratch, and material of the refractive index is larger, so we need to plating system high hardness minus reflection film on its surface to protect and higher transmittance.In its common spectral range, the scattering is very low. When used in high power laser device, the absorption of the material must be strictly controlled and internal structure defects, and uses the minimum damage degree of polishing technology and coating process of the highest quality.
