tgg crystal

 

Terbium gallium garnet (Tb ₃ Ga ₅ O ₁₂ , 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). The TGG crystal possesses a large verdet constant (35 RadT ⁻¹ m ⁻¹  at 1064 nm), high thermal conductivity (7.4 Wm ⁻¹ K ⁻¹ ), low optical losses (<0.1% / cm) and high laser damage threshold ( > 1 GW / cm ² ). Therefore, it is an attractive Faraday-rotating crystal suitable for constructing magneto-optical isolators, magneto-optical switches, magneto-optical modulators and so on .Widely used in YAG, Ti-doped sapphire and other multi-stage amplification, ring type, seed injection laser.
