Undoped YAG

●non-birefringent
●High bulk damage threshold
●high thermal conductivity
●High index of refraction, facilitating low aberration lens design
●Low stress and high optical quality

EMAIL

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.
