Abstract : During the course of this contract, solid progress was made in both the development and understanding of rare gas halide lasers. Initially, to comprehend the major processes which occur in the laser plasma, we developed a long pulse kinetics experiment which simulated closely the laser kinetics. The experiment was used to investigate the kinetics of the XeF laser and, later, the XeC1 laser, both with neon as a diluent. In general, the experiment provided information on the fluorescence yield, the formation efficiency and the apparent quenching rate constants for the upper laser level. For XeF, the results of the experiment served as a basis for a computer code which simulated long pulse operation of the XeF laser. The code was used to investigate various processes in the laser such as formation, absorption and ground state bottlenecking. The role of the XeF(C) was unraveled using the model, and, also the effects of halogen donor depletion. For XeC1, the experiment has provided information on the fluorescence yield and apparent quenching rate constants for the XeC1(B) state. Preliminary modeling analysis of XeC1 indicates that the formation efficiency is close to 100 percent.
