EXPERIMENTAL-STUDY AND MODELING OF PHOTOT RIGGERED XECL EXCIMER LASERS

We have experimentally and theoretically studied the phototriggered Xe Cl laser, A complete set of time resolved experimental diagnostics has been implemented on a small active volume laser, and the measurements compared with a OD-model predictions. This model includes a detailed kinetic of the XeCl molecule, and the effect of the gas temperature gr owth during the development of the discharge. The Boltzmann equation i s solved using a two-term expansion method which has been shown to be accurate with short CPU-time. A coherent set of electron-HCl collision cross sections has been also established and used in the calculation. The applicability limits of such a OD-model have been precisely check ed, and the performances of larger active volume lasers have been pred icted.
