Terbium Gallium Garnet | TGG

Terbium Gallium Garnet (TGG) is a magneto-optical crystal used in Faraday isolators and rotators for 400-1100nm wavelengths (excluding 475-500nm). It offers a high Verdet constant, low optical absorption, and strong laser damage resistance, making it ideal for laser systems and optical communications. HM supplies 4-inch TGG blanks, including TSAG-grade crystals, for advanced applications like amplifiers and ring lasers.
