Nd:YAG is the earliest and most famous laser host crystal. Since it combines great advantages in many basic properties,Nd:YAG is the ubiquitous presence for near-infrared solid-state lasers and their frequency-doubler, tripler, and higher order multiplier.
It is widely used in industrial, medical, and scientific fields.. Nd:YAG crystals 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.
