what's terbium gallium garnet(Tb3Ga5O12)TGG crystals?

Terbium Gallium Garnet (TGG) is the right crystal material for Farady devices. The Farady ratator is made up of a TGG rod contained in a special designed magnet. The polarization of a light beam passing through the rotator makes rotation.

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. 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.

The magneto-optical crystal TGG is an optimum material for Faraday devices 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 direction of rotation is only dependent on the direction of the magnetic field and not on the direction of propagation of the light beam.The optical isolator consists of a 45 degree rotator set between two suitably arrayed polarizers which allow a light beam to pass through in one direction only. With a combination of excellent properties, such as large verdet constant,low light loss, high thermal conductance and high light damage threshold,TGG is the unique material for Farady devices. It is widely used for YAG lasers and Ti:sapphire tunable lasers,ring lasers ,etc.
