Nd:YAG Laser Mirror, High-Energy, 50.8 mm, 45°, 1064 nm, S2 Ground

The 20QM20HM.15-G is a 50.8 mm diameter, 9.65 mm thick High Energy Nd:YAG Laser Mirror coated for the fundamental 1064 nm wavelengths. Its reflectivity at this wavelength is greater than 99% for both s- and p-polarization, and it is optimized for 45° AOI. The back surface is ground.
UV Fused Silica Substrate
Fused Silica is synthetic amorphous silicon dioxide of extremely high purity. This non-crystalline, colorless silica glass combines a low content of inclusions with high refractive index homogeneity, a very low thermal expansion coefficient, and excellent transmittance in the wavelength regime from UV to NIR. As a result, these mirrors will perform better with temperature fluctuations and is ideal for high-energy laser applications due to its high energy damage threshold.
