NEWPORT 优铂特 10QM20HM.45-G 高能量 Nd:YAG 激光器
Nd:YAG Laser Mirror, High-Energy, 25.4 mm, 45°, 354.7 nm, S2 Ground
The 10QM20HM.45-G is a 25.4 mm diameter, 6.35 mm thick High Energy Nd:YAG Laser Mirror coated for the fundamental 354.7 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.
