KINETIC MODELING OF SELF-SUSTAINED DISCHARGE XeCl LASER AND ITS INFLUENCE ON THE EFFICIENCY
要約
A Photon emission phenomena, with energies about electron Volts, has been experimentally observed in excimers molecules. This category of diatomic molecules gave rise to important researches and developments in lasers technology. The present work is a zero-dimensional modeling of an electric discharge at high pressure, for excimer laser, coupled with the external circuit. In this model, the plasma generated by impulsional discharge is represented by one or more resistances in parallel whose conductivity is proportional to the electron density. The temporal variations of this electronic density are described using a whole of differential equations translating the kinetic of the medium. Rate coefficients are obtained by solving the Boltzmann equation. Detailed description of XeCl molecule and of the associated kinetic have been taken into account, together with the effect of the gas mixture composition on power deposition and the spatial uniformity of the plasma. The model predictions have been compared with the experimental results.
