Unadulterated Yttrium Aluminum Garnet (Y3Al5O12 or YAG) is a new substrate and optical material that can be used for both UV and IR optics. Particularly useful for high temperature and high energy applications. Mechanical and chemical stability of YAG is similar to that of Sapphire.
1. Non-double refraction
2. Exceptionally tough and durable
3. High thermal conductivity
4. High bulk damage threshold
5. High index refractive
