Our high power Faraday optical isolators can be used in the 1010 nm to 1080 nm wavelength range, up to 50 W, and provides double escape ports for applications where rejected power exceeds 0.5 W. These isolators offer 1 MW/cm2 CW damage threshold and 10 J/cm2 @ 10 ns or 1 J/cm2 @ 8 ps pulse damage thresholds.

Features
High Power Fused Silica PBS Cube
Our high power Faraday optical isolators use high damage threshold Fused Silica polarizing beamsplitter (PBS) cubes that are optically contacted rather than cemented. They also utilize double escape ports for added application flexibility.
1/2 Waveplate Option
We offer versions with an added zero order 1/2 wave plate (-W models) at the output stage so that the direction of the output beam polarization can be rotated to a desired direction.
High Efficiency Performance
The TGG crystal utilized in our Faraday isolators creates a large Verdet constant that ultimately describes the strength of the Faraday effect and provides effective isolation of back-reflected light. Additionally, these isolators have low absorption as a function of the TGG crystal and polarizers, resulting in reliable transmission of light in the forward direction.
Easy Placement into Optical Train
These isolators are packaged in a compact, cylindrically-shaped magneto-optic device with a base plate for easy mounting into an optical train.
