Nd: YAG crystal, also called a neodymium-doped yttrium aluminum garnet crystal, is a laser medium crystal with excellent thorough residential properties used for solid-state lasers. The atoms in the Nd: YAG crystal are excited by the flashlamp, and also the crystal generates intensified light that multiplies at a certain wavelength (1064 nm). Nd: YAG is one of the reputable laser crystals acquired by doping Nd ions into YAG crystals.
