TGG single crystal

TGG single crystals are the best magneto-optical materials for making Faraday rotators and isolators. A Faraday rotator consists of a TGG crystal rod and a specially designed magnet. The polarization direction of a light beam passing through the magneto-optical material will be deflected under the action of a magnetic field. The deflection direction is only related to the direction of the magnetic field and is independent of the propagation direction of the light beam.
