We present the results of modeling the radial profile of the gas temperature in metal vapors active media, in particular, copper vapor. The modelling was carried out using a detailed kinetic model of the active medium for gas-discharge tubes (GDT) of various diameters, operating at repetition rates of 10 and 20 kHz. The effect of the operating frequency and the GDT diameter on the gas temperature profile was shown.
