Paper Abstract

The gains were measured for the lines in the traditional band 0001-1000, 0001-0200, in the second band of the 0002-1001 sequence, and in the hot band 0111- 1110 emitted by the active medium of an electric-discharge carbon-dioxide module. The experimental results were used in a generalized theoretical model to find the translation and vibrational temperatures and the concentration of the active molecules. The Fermi resonance between the 1000 and 0200 did not ensure a Boltzmann distribution of their populations under the conditions in the electric-discharge module. The degree of dissociation of the carbon-dioxide molecules in the discharge did not exceed 22% when the maximum input power density was near 6 W/cm3.
