Newport MKS Nd:YAG Laser Mirror, High-Energy, 25.4 mm, 45°, 1064 & 532 nm, S2 Polished 10QM20HDM.15

The 10QM20HDM.15 is a 25.4 mm diameter, 6.35 mm thick High Energy Nd:YAG Laser Mirror coated for the fundamental 1064 nm and second harmonic 532 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 polished. 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.
