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.
