Undoped YAG
Undoped YAG is a substrate and window crystal that can be used for both UV and
IR optic. It is particularly useful for high temperature and high
energy applications. The mechanical stability of YAG is similar to Sapphire,
but YAG is not birefringent and is available with high optical homogeneity.
