Product Details
Terbium gallium garnet (Tb3Ga5O12, TGG) is a high-performance magneto-optical crystal in the visible and infrared bands. TGG crystals have high Feld constant, low absorption coefficient, high thermal conductivity, high laser damage threshold, and excellent optical quality. All these advantages make TGG crystal suitable for building Faraday effect devices, and make up for the shortcomings of YIG crystal in the visible and near-infrared spectral regions. As an ideal magneto-optical material, TGG crystal has attracted widespread attention as an optical isolator for fiber lasers in the visible and infrared bands.
