    Magneto Optical Terbium Gallium Garne TGG Single Crystal

    TGG Single Crystal( Terbium Gallium Garne )Manufacturer China


    Description:


    Terbium gallium garnet (Tb3Ga5O12, TGG) is a crucial category of magneto-optical materials for use in the visible and the near-infrared spectral regions((400-470nm and 500-1500nm)). TGG singlecrystal is an excellent magneto-optical crystal used in various Faraday device s(Rotator and Isolator) in the range of 400nm-1100nm, ( excluding 475 - 500nm.). which can replace YIG crystal


    Features:

    • Large Verdet Constant (Typical 35 dB,Up to 40dB)
    • Low optical losses (<0.1%/cm)
    • High thermal conductivity (7.4W m-1K-1).
    • High laser damage threshold (>1GW/cm2).
    • TGG has twice the Verdet constant of a terbium-doped glass.
    • Thermal conductivity is an order of magnitude greater than typical glass.

    Applications:

    • Faraday Rotator;

    • Optical Isolator.

    • Magnetic sensor
