TGG Rod for Isolator

Product Description

TGG Crystal

TGG (Terbium Gallium Garnet) single crystal is currently the best and widely used magneto-optical material in Faraday rotator and isolator due to its extremely high Verdet constants in the range of 400nm-1100nm(excluding 475-500 nm). By placing a rod of this material in a strong magnetic field, Faraday rotation angles of over 45° can be achieved. This allows the construction of Faraday rotators which are the principal component of Faraday isolators, devices which transmit light in only one direction.
