Product Details
10x10mmt Terbium gallium garnet (TGG)crystals substrate wafer for
laser device
Product Type: Yttrium aluminum garnet (YAG) is an isotropic crystal with cubic
symmetry. It has excellent optical and thermodynamic properties.
Its mechanical properties and chemical stability are close to that
of sapphire crystal, and there is no birefringence effect of
sapphire. Pure YAG crystals have a high transmittance in the range
of 0.25 ~ 5um and no absorption in the range of 2 ~ 3μm, while
glass has a strong H2O absorption band. Therefore, undoped pure YAG
crystals are a new type of substrate and window materials for
ultraviolet and infrared optical devices. At the same time, the
excellent physical and chemical properties and optical properties
of YAG crystals make them important optical applications in high
temperature and high energy physical environments.
The application of YAG material:
Undoped pure YAG crystal is a new type of substrate and window
