Tb₃Ga₅O₁₂ (TGG) Crystal Substrates

Garnet structure Tb₃Ga₅O₁₂ (TGG) single crystals have high Verdet constant, low optical absorption coefficient, and high laser damage threshold. These properties make it suitable for magneto-optical isolator application. 

MSE Supplies offers different size, orientation and polishing requirements of TGG crystals and substrates, please contact us for customization.
