Although Nd:YAG was invented in the Sixties last century, it has been and is still the most commonly used solid-state crystal material. Nd:YAG crystals are wildly used in all types of solid-state lasers 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.
