High Power Faraday Rotator and Isolator

The High Power 1064nm Free Space Isolator is characterized with low insertion loss, high isolation, high power handling, It is ideal for fiber laser and instrumentation applications.

The High Power 1064nm Free Space Isolator is characterized with low insertion loss, high isolation, high power handling, high return loss, excellent environmental stability and reliability. It is ideal for fiber laser and instrumentation applications.

Optical isolators, also known as Faraday isolators, are magneto-optic devices that preferentially transmit light along a single direction, shielding upstream optics from back reflections. Back reflections can create a number of instabilities in light sources, including intensity noise, frequency shifts, mode hopping, and loss of mode lock. In addition, intense back-reflected light can permanently damage optics. In high-power applications, back reflections can cause instabilities and power spikes. That is why we need a optical isolator.

For wavelength of 1064nm, PM and non-PM types are available, fiber can be customized, with power conditions of CW or Pulse and Power Handling of 5W, 10W, 20W(30W, 50W can be customized).

If you do not see a standard isolator that meets your needs, we welcome the opportunity to review your desired specification and quote a custom isolator. Requests for custom fiber pigtails, different wavelengths and handling power of operation or other specific needs will be readily addressed.
