Pure YAG Yttrium Aluminum Garnet 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. The mechanical and chemical stability of YAG is comparable to sapphire crystal, but YAG is unique with no birefringence which is extremely important for some optical applications.
