TGG Crystal(Faraday Rotato)

TGG (Terbium Gallium Garnet) single crystal is the best and magneto-optical materials for the production of Faraday polarizer and isolators, which can be applied in the range of 400-1100 nm wavelength (excluding 470-500 nm). Faraday polarizer is composed of the TGG crystal rod and a special designed magnet. The polarization of the beam through the magneto-optical materials deflexes and the direction of deflection only has some relations with the direction of the magnetic field and has nothing to do with the direction of the beam propagation. Optical isolator is an optical component  formed from a 45-degree deflexed rotator and a proper placed which allows the transmission of polarized light in only one direction.

The Major Advantages

The TGG magneto-optical crystal has a constant, high thermal conductivity, low-loss and high laser damage
threshold, widely used YAG, Ti:Sapphire, and other multi-level amplification, ring, seeds into laser
