TGG (Terbium Gallium Garnet) Crystal

TGG is a garnet-structure single crystal widely recognized as the industry-standard magneto-optical material for Faraday rotators and optical isolators, particularly in the near-infrared wavelength range.

TGG crystals are valued for their high Verdet constant and are used extensively in laser systems requiring optical isolation, including high-power fiber and solid-state laser applications.

Custom sizes and specifications are available upon request — please contact us to discuss your requirements.
