Collisional Dynamics, Lasing And Stimulated Raman Scattering In Optically Pumped Cesium And Potassium Vapors, Kirk C. Brown

Theses and Dissertations

This dissertation explores collisional dynamics, lasing and stimulated Raman scattering in cesium and potassium vapors. The spin orbit mixing and quenching cross sections of several buffer gas species are measured. The ne-structure mixing cross sections for He, CH₄ and C₂H₆ are 14±3, 35±6 and 73±10 °A², respectively. The ²P_3/2 state is quenched more rapidly than the ²P_1/2 state. A pulsed blue laser operating via direct excitation of the cesium 7²P_3/2 state is demonstrated. A theoretical model is extended and compared with experimental results. The maximum output …
