Paper Abstract

A numerical excimer laser model based on the Boltzmann-code developed by Rockwood1 was used to simulate several discharge pumped XeC1-lasers. Modifying this code the amount of CPU-time necessary for the simulation of one discharge pulse could be reduced for about 70%. Extending the reaction kinetics listed by Stielow, Hammer, B&- ticher2 with electron molecule-ion recombination reactions a better agreement of calculated electron densities with experimental values was obtained. The relative courses of exctited Xe population densities agree better with the measured ones too, but the calculated number density values are a factor 2.2 too large, which may be due to the simple xenon model taking into account two model levels for excitation only. To reproduce the laser output energies measured by Cirkel3 and Steyer4 the values of the rate constants for XeCl* and XeCl-quenching taken from literature have to be changed. A more correct description of these reactions and of the stimulated emission cross section is in preparation. This extended model will be checked experimentally by temporal and spectral resolved measurement of the small signal gain.
