Nd: YAG crystals are the most widely used solid-state laser materials. These crystals are characterized by a relatively narrow gain bandwidth, which allows for high gain efficiency and a low laser threshold. Nd: YAG crystals possess excellent thermal and mechanical properties. High optical quality and large diameter Nd: YAG crystals can be obtained using the Czochralski method.
Nd YAG crystal for sale is widely used in laser systems due to its excellent optical and thermal properties.
Isotropic crystals (cubic symmetry)
- High thermal conductivity
- Obtain high optical quality and large diameter spots with Czochralski
The low laser threshold and wide absorption band near 808 nm coincide with the emission of the AlGaAs laser diode
