Nd:YAG Laser Crystal
Nd:YAG Crystal (Nd:Y3Al5O12) is the most widely used solid state laser crystal. Nd:YAG laser crystal are wildly used in all types of solid-state laser systems-frequency-doubled continuous wave, high-energy Q-switched, and so forth. Its good fluorescent lifetime thermal conductivity and physical strengths makes it suitable for high power lamp pumped laser.
