Tgg Terbium Gallium Garnet Laser Crystal - China

Terbium Gallium Garnet(TGG), as a magneto-optical crystal, is an optimum material for Faraday devices (Rotator and Isolator) in the range from 400nm-1100nm, excluding 470-500nm.

The Faraday rotator consists of a TGG rod contained inside a special designed magnet.

The rotation sense of the polarization of a light beam passing through the rotator only depends on the direction of the magnetic field and not on the direction of propagation of the light beam.

The optical isolator is a Faraday rotator set between two suitably aligned polarizers which allows a light beam to pass through in one direction only.

Photonchina TGG has a combination of excellent properties such as large Verdet constant, low light loss, high thermal conductance and high light damage threshold which makes it a unique material for Faraday devices particularly suitable for YAG lasers and Ti: sapphire tunable lasers, ring lasers and seed injected lasers.
