High Power Faraday Rotator and Isolator

Faraday rotators change the polarization state of light traveling through it. The output polarization state is rotated by 45 degrees with respect to the input polarization. When combined with a mirror, the reflected light is rotated by another 45 degrees, resulting in a 90 degree rotation. In addition, the polarization handedness is reversed by the mirror. This results in a reflected polarization that is orthogonal to the original polarization. This is useful when used in interferometers,because polarization changes through the fiber are cancelled out on the return journey.


The high power isolator series includes in-line type, beam expanded isolator, fiber in and free space out isolator and free space isolator etc. 1064nm High Power Free Space Isolatoris one of the free space in and out type isolator. They’re characterized with low insertion loss, high isolation, high power handling, high return loss, excellent environmental stability and reliability. They are ideal for fiber laser and instrumentation applications.
