Neodymium Doped Gadolinium Gallium Garnet Crystals and Substrates Description

Neodymium Doped Gadolinium Gallium Garnet Crystals and Substrates (Nd:Gd₃Ga₅O₁₂) has excellent thermal conductivity and mechanical properties. Compared with other Nd³⁺ doped crystals, such as Nd: YVO₄, Nd: GdVO₄, Nd: YGdVO₄ and Nd: YAG, Nd: GGG crystals do not have an optically inhomogeneous area called “nucleus”. Consequently, it can support a higher Nd³⁺ doping atom number fraction. Therefore, it is considered to be the best working crystal for solid-state heat capacity lasers.

Nd: GGG can be used as an LD pump crystal. Nd: GGG has a large stimulated emission cross-section and a high laser efficiency as well as a low threshold. In addition, this material has the advantages of high specific heat and high thermal conductivity, and similarly the long emission time. Therefore, it is the first choice for high-power laser working materials for LD pumps.
