Abstract : An optical isolator for use in a laser system to protect the system from undue 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 polarizaton will be rotated without introducing ellipticity into the beam polarization. (Author)
