Nd:YAG is the earliest and most famous laser host crystal, and it has been widely used laser crystal for solid-state laser.
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.
