Excimer Lasers
Abstract
The results of a theoretical and experimental program addressed to demonstrating the feasibility of a high-energy alkali-rare gas excimer/dimer laser are reported. The major theoretical accomplishments are the development of a detailed model for flashlamp pumping of all the alkali-xenon excimer/dimer systems and for discharge pumping of the potassium-xenon and potassium-argon systems. The models predict that laser oscillation is attainable under practical laboratory conditions on both the excimer and dimer bands of these systems. Major accomplishments of the experimental program are a measurement of the stimulated emission coefficient on the K-Xe excimer band during flashlamp pumping which was consistent with the model; the attainment of a 1 microsec, pulsed diffuse discharge through an aerosol-free K-Ar mixture under conditions predicted by the model to be sufficient for achieving laser oscillation on the excimer and dimer bands and the attainment of preliminary absolute fluorescence data on the discharge pumped K-Ar excimer band indicative of a resonance level concentration within an order of magnitude of that predicted by the model.
