Abstract

Using the results for the time- and spatially-averaged electron temperature, which were previously obtained by the lineratio method of optical emission spectroscopy for several metal halide vapor lasers excited in nanosecond pulsed longitudinal discharge and analytically solving steady-state heat conduction equation for electrons as well, radial distribution of time-averaged electron temperature, i.e. spatially-resolved electron temperature, is obtained. 2D (r, t) numerical solution of nonstationary heat conduction equation for electrons is also found out.
