ABSTRACT:
An optical isolator for use in a laser system to protect the system from ue absorption of unwanted scattered light energy. The isolator employs the use of a Faraday rotator combined with the application of an external magnetic field to split absorption lines into two components. By adjusting the magnetic field strength light of a certain frequency passes through the rotator at a spectral position between the split absorption line components. Thus absorption is greatly reduced and the plane of polarization will be rotated without introducing ellipticity into the beam polarization.
