This report describes the results of a program directed toward the development of new lasers in the infrared and visible regions of the spectrum, utilizing electron-beam-stabilized electric discharge excitation. The first laboratory observations of laser emission from HF and DF excited directly by an electric discharge were made. The effectiveness of vibrational transfer from H2 and D2 to HF and DF, respectively, was verified. A quantitative model of the kinetics of the electric discharge and the vibrational populations of H2 and HF was formulated for ArH2HF mixtures. A model for long pulse visible laser emission from electronically excited molecules was formulated that involves rapid collisional quenching of the vibrational energy of the electronic states. The application of this approach to N2 electric discharge lasers was explored through fluorescence emission studies. The effect of energy pooling was studied. The effect of various additives such as He, Ar, SF6, and C2H6 on the populations of several vibrational levels of each of these excited states was investigated.
