The mechanical and chemical stability is comparable to sapphire crystal, but YAG is unique with non-birefringence and available with higher optical homogeneity and surface quality.
Up to 3" YAG boule grown by CZ method, as-cut blocks, windows and mirrors are available.
Advantages of Undoped YAG:
High thermal conductivity, 10 times better than glasses;
Extremely hard and durable;
Stable mechanical and chemical properties;
High bulk damage threshold;
High index of refraction, facilitating low aberration lens design.
Features of Undoped YAG:
Transmission in 0.25-5.0 mm, no absorption in 2-3 mm;
High thermal conductivity;
High index of refraction and Non-birefringence.
