Abstract

The cathode region and the positive column one at DC discharge and acoustoplasma mode are considered. The spectrum and intensity of the lines of nitrogen and other components of the working mixture of a CO2 laser are shown. Dependence of the intensity of the certain spectral lines and the integral spectrum in the visible range (300 - 800 nm) on the frequency and on the modulation depth of the discharge current are obtained experimentally. The spectra of factory mixture of a CO2 laser and a mixture of CO2: N2: He = 1: 1: 8 are compared.
