Nd:YAG Description

Nd:YAG (Neodymium-doped Yttrium Aluminum Garnet) is the earliest and most famous laser crystal for solid-state laser. Nd:YAG has many typical features: high gain, low threshold, and high efficiency. The fluorescence lifetime of Nd:YAG is twice that of Nd: YVO4 and its thermal conductivity is also better. It can be used to provide a green laser for SHG at 1064nm.
