Nd:GGG (neodymium doped gadolinium gallium garnet)

Chemical formula: Nd:Gd3Ga5O12 

Nd:GGG single crystal has excellent properties, such as high mechanical strength, chemical stability, thermal conductivity and thermal capacity, wide absorption bands at around 808 nm and long fluorescence lifetime.  Because of these unique properties, Nd:GGG crystal has been considered as one of the best materials for the high average power solid-state laser. The applications include semiconductor laser pump and can be operated with CW-laser and pulse laser.
