Nd:YAG Crystal
Theory of Optics
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.
