YAG Optical Crystals
Undoped Yttrium Aluminium Garnet (Y3Al5O12 or YAG) is a new substrate and optical 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 similar to that of Sapphire.
1.Non-birefringence
2.Extremely hard and durable
3.High thermal conductivity
4.High bulk damage threshold
5.High index refractive
