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

Basic properties of Undoped YAG:

• Density 4.5g/cm3
• Transmission Range 250-5000nm
• Melting Point 1970°C
• Specific Heat 0.59 W.s/g/K
• Thermal Conductivity 14 W/m/K
