TGG Crystals

The magneto-optical crystal TGG crystal is an optimum material for Faraday devices (Rotator and Isolator) in the wavelength range 400 nm-1100 nm, excluding 470-500 nm. TGG crystal 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 an unique material for Faraday devices particularly suitable for YAG lasers and Ti:sapphire tunable lasers, ring lasers and injection-seeded lasers.
