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 careful splice and component orientation that compensates for component birefringence of the various ring elements that alter the polarization state and azimuth. Further, such polarization transformation is minimized by careful deployment of the non-polarization component.
