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