Neodymium-doped Yttrium Aluminum Garnet Crystal (Nd:YAG)
Neodymium doped yttrium aluminum garnet (Nd: YAG) crystal is an essential laser crystal widely used in industrial, medical, and scientific fields. Nd: YAG crystal's main advantages are low light threshold, high gain, high efficiency, low 1064 nm loss, high optical quality, good thermal conductivity, thermal shock resistance, and high mechanical strength. Those characteristics make Nd: YAG becoming most suitable and commercial laser crystal for the mode laser. Nd: YAG crystals are also widely used in various solid-state laser systems, such as frequency doubling continuous waves, high energy Q switches, and inverted cavities.
