Abstract

A blue alkali laser operating by direct optical excitation of the 7²P_3/2 state of cesium is demonstrated. A mixture of cesium vapor and various buffer gases (⁴He, CH₄, C₂H₆) were pumped with the output of a pulsed dye laser in a heated glass cell. The spin-orbit mixing and fluorescence quenching cross sections were calculated for each buffer gas using the time-dependent D1 (459 nm) side fluorescence. At certain temperatures and buffer gas pressures, a spatially coherent blue beam is produced in the forward direction. An analysis of the spectrum shows this beam contains both D₁ amplified spontaneous emission (ASE) and Stimulated Raman Scattering (SRS).
