Magneto Optical Crystals Cubic TGG Single Crystal For High Power
Optical Isolators
Promising Materials TGG Single Crystal for High Power Laser
Isolators
Currently, terbium gallium garnet (Tb3Ga5O12, TGG) is the most
common single-crystal Faraday rotator used in optical isolator
applications. Because TGG melts congruently at a temperature of ~
1825 °C, large crystals can be grown using the Czochralski
technique.
