High Power Polarization Maintaining (PM) Optical Isolator series includes in-line type, beam expanded isolator, fiber in and free space out isolator and free space isolator etc. They’re characterized with low insertion loss, high isolation, high power handling, high return loss, excellent environmental stability and reliability. Optical Isolators are optical devices that allow light to be transmitted in one direction only. They are most often used to prevent any reflected light from entering the source, thus preventing any feedback problems, it has been widely used in fiber laser system.For wavelength of 980nm, 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.
