TGG (Terbium Gallium Garnet Crystal)


TGG crystal is an excellent magneto-optical crystal used in various Faraday devices(Polarizer and Isolator) in the range of 400nm-1100nm, excluding 475-500nm.

 

Advantages

· TGG has twice the Verdet constant of a terbium-doped glass.

· The thermal conductivity of crystalline TGG is an order of magnitude greater than a typical glass.

· Optical losses are lower for TGG than Tb-doped glasses.

· The combination of the above factors make TGG better suited to high average power applications. The principal limiting factor is thermally induced beam distortion. Beam distortion is less for TGG than Tb-doped glasses under the same power loading level.

Glan Thompson Polarizer alpha-BBO & Calcite Glan Thompson Polarizer
alpha-BBO & Calcite Glan Thompson Polarizer
Glan Thompson Polarizer is made of two α-BBO or calcite prisms cemented together. It has a wavelength from 200nm to 2300nm. α-BBO polarizer can be used from about 200nm to 1100nm, and calcite polarizer can be used from 350nm to 2300nm.   This type polarizer has higher extinction ratio than air spaced polarizer. And it has the widest field angle of any design. For example, α-BBO Glan Thompson Polarizer has an angular field lager than 15 degree.
