Optical Isolators & Faraday Rotators for Laser Systems

Optical isolators and Faraday rotators provide essential protection for laser systems by controlling polarisation and preventing unwanted optical feedback. Photonic Solutions supplies a comprehensive range of InPut Optica Faraday devices for CW, pulsed, ultrafast and high-power laser applications, covering wavelengths from the UV and visible through to the mid-infrared.

An optical isolator allows laser light to propagate in the desired direction while strongly attenuating back-reflected light. This helps protect sensitive laser sources, seed lasers and amplifiers from optical feedback that can cause instability, noise, mode hopping or damage. Faraday rotators can also provide precise polarisation rotation where required.

Our portfolio includes free-space optical isolators, broadband isolators, high-power Faraday isolators, dual-stage isolators, water-cooled isolators and isolators for femtosecond laser systems. Available configurations include different clear apertures, wavelength ranges, output geometries, coatings and mounting options.

For demanding laser systems, we can help you select an isolator based on wavelength, optical power, pulse duration, beam diameter, damage threshold, isolation ratio, insertion loss and polarisation requirements.
