YAG laser machine part

Undoped YAG is a new substrate and window material that can be used for both UV and IR optics. Undoped YAG is a new substrate and window material that can be used for both UV and IR optics. It is particularly useful for high temperature and high-energy applications. YAG shows no trace absorption in the 2-3mm region where glasses tend to be highly absorbent due to the strong H2O band. Sapphire is also slightly birefringence. The mechanical and chemical stability of YAG is similar to Sapphire, but YAG is not birefringence and is available with high optical homogeneity.Based on the patented new growth technique of Temperature Gradient Technique (TGT), ATOM has successfully produced large size of f50´150mm and high quality undoped YAG.Wide Transmission Range:Useful from 250nm to 5000nmNo absorption in the 2-3mmExcellent Thermal and Opto-Mechanical Properties:High thermal conductivity, 10 times better than glassesExtremely hard and durableNon-birefringenceStable mechanical and chemical propertiesHigh bulk damage thresholdHigh index of refraction, facilitating low aberration lens designProperity:
