    Product Info | TGG Crystal Series

    Author:Optizone Technology (Shenzhen) Limited Click: Time:2022-04-25 11:30:47


    Terbium gallium garnet (tb3ga5o12, TGG) crystal has large magneto-optical constant, low optical loss, high thermal conductivity and high laser damage threshold. It is widely used in multistage amplification, circular and seed injection lasers such as YAG and Ti doped sapphire. TGG single crystal is the best magneto-optical material for making faraday rotators and isolators, with a suitable wavelength of 400~1100nm (excluding 470~500nm).

     

    In view of the advantages of TGG crystal, Optizone Technology uses TGG crystal to build a series of products, which are mainly used in pulse and ultrafast laser, including isolators, circulators, etc.
