Abstract
Rotational displacement of the birefringent lasing medium in a lasing cavity containing a polarizing element varies the spectral width of the generated laser light. The combination in a lasing cavity of a birefringent lasing medium, a polarizing element, a tuning element and a birefringent compensator permits output of narrow bandwidth spectrally tuned laser light continuously over the total gain bandwidth of the lasing medium by rotating the lasing medium, tuning to desired wavelength, and adjusting the birefringent compensator to optimize output of laser light.
