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.

Up to 5 W of forward power handling
>33 dB isolation
>95% transmission
Compact isolator design
532, 638 and 785 nm center wavelengths
1/2 waveplate option (-W models)

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.

Mounting to a Table, Stage, or Post

Newport offers the V-Block mount, a cost-effective way to mount and secure cylindrical devices, including these Compact Faraday Optical Isolators. The block can be attached directly to an optical table, tip/tilt or translation stage, or it can be post-mounted.

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
