A self-consistent computational model of electrodynamic and thermogasdynamic processes in electric-discharge lasers

The pager deals with a self-consistent computational electrodynamic and the rmogasdynamic model of the working chamber of a gas-discharge laser with a segmented cathode. The computational model is based on a set of Navier-Stok es equations, with the effective turbulent viscosity described within the k -epsilon model of turbulence, energy equation for partly ionized gas, equat ions of motion of charged particles (electrons and ions) in a diffusion-dri ft approximation, and continuity equation for electric current. The model i s used to investigate the processes in the gas-discharge chamber of a laser with a segmented cathode and continuous anode. The calculations are perfor med for the real parameters of technological CO2 lasers.
