High Thermal Conductivity Terbium Gallium Garnet TGG Crystal Rods

Introduction :

Terbium Gallium Garnet (TGG) is a kind of synthetic garnet, a magneto-optical crystal with a high level of thermal conductivity for Faraday rotators and isolators. It can be used in optical isolators for laser systems, in optical circulators for fiber optic systems, in optical modulators, and in current and magnetic field sensors.
