- Spin flip Raman laser operation in InSb was studied using different cavity configurations in which the laser crystal was placed simultaneously in the pump and Raman laser resonators. The two configuraions studied were: an anti-resonant ring end mirror for the pump cavity with the crystal inside the ring; the pump and Raman cavities coupled through a Brewster flat beam splitter with low loss orientation for the pump cavity. The properties of the ring configuration were studied with emphasis placed upon pump resonator losses. This configuration has not yet lased. The absorption by InSb of pump power was measured as a function of wavelength between 5.2 to 5.5 microns. Optimized InSb crystal lengths were determined from the measured pump power absorption coefficient and new crystals were procured for the Brewster flat configuration. This configuration was successfully lased and tuned using the short crystals. Stimulated Raman scattering from Landau levels in InSb was observed. The final quarterly period of the Contract will be devoted to optimization studies of the two resonator configurations.
