Different Doping Levels High Optical Quality Nd:YAG Laser Crystals For High Power Laser
Products Description:
Undoped YAG Laser Crystal is an excellent material for UV-IR Optical Windows, particularly for high temperature and high energy density application. It's different from Nd:YAG Crystal.
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
- Non-birefringence
- 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
