Abstract

Describes a kinetics model for e-beam excited XeCl lasers using Ne/Xe/HCl gas mixtures. The model has been validated by comparison with measure transient absorption in Ne/Xe mixtures, as well as by comparison with measured laser performance under a range of conditions. A key feature of the model is the inclusion of a fast three-body charge exchange process between Ne₂⁺ and Xe which provides an efficient channel for XeCl* formation through ion-ion recombination. Xe⁺₂ is predicted to be the dominant absorber in Ne/Xe mixtures with with xenon fractions greater than 0.75 percent, while Cl^- is predicted to be the major absorber in optimum laser mixtures.
