Low Optical Loss Dia 10*15 Mm TGG Crystals Magneto Optical Material

Introduction :
Terbium Gallium Garnet (TGG) is a kind of synthetic garnet ,an 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.
