Compact Faraday Optical Isolators
Compact Faraday Optical Isolators
The Compact Faraday Optical Isolator is essentially a uni-directional light valve. The compact design makes it highly suitable for OEM integration. They are available with a 2- or 4-mm clear aperture and in a variety of wavelength ranges to allow for optimal isolation and transmission at specific wavelengths. The devices contain optically-contacted polarizing beamsplitter cubes, resulting in high transmission compared to other available isolators.

Features
High Transmission Polarizing Beamsplitter Cube
Our compact isolators contain optically contacted polarizing beamsplitter cubes that provide high transmission. With more photons available for your application, diodes can be run at lower currents, extending the diode lifetime.
1/2 Waveplate Option
We offer versions with an added zero order 1/2 wave plate (-W models). The waveplate is installed at the factory and cannot be adjusted. Should you need to adjust the waveplate please contact us.

Applications
Common applications for compact isolators include:
- Eliminating frequency instability in single-frequency lasers, such as diodes and OPSLs
- Preventing mode-hopping in external cavity diode lasers
- Eliminating parasitic oscillations due to ASE in amplified laser systems
