A comprehensive data set from experiments and model calculations for investigating the behavior of optically pumped supersonic beam lasers is presented. The results for Na/sub 2/ demonstrate the roles of stimulated Raman scattering and one-photon population inversion on the gain for collinear optical pumping of supersonic beam gain media for both circular and slit nozzles. For the wavelengths investigated, Raman gain dominates, and an effective photon conversion of greater than 24% is realized. Lasing both with and without frequency-selective elements is studied. Laser transitions terminating on a large range of vibrational levels of the /ital X/ state are observed. The density-matrix calculations for the gain coefficient include the dynamics of the expansion and the influence of condensation. These results show good qualitative agreement with the experimental data.
