ABSTRACT:
The present invention relates to a tuneable ring laser with an output having a fixed, stable linear state of polarization with a fixed and known azimuth. The state of polarization at the output is fixed by compensating for component birefringence of the various ring elements that alter the polarization state and azimuth.
