Abstract
The technique for multifrequency diagnostics of a vibrational nonequilibrium gas mixture that contains CO2 molecules is proposed. The technique uses data on unsaturated gains at lines of the 0001–[1000, 0200]I, II and 0002–[1001, 0201]I, II transitions obtained with the help of a tunable CO2 laser. Results of the study of the influence of accuracy of gain measurements and the number of sensing lines on errors in determining populations of vibrational levels and gas mixture translational temperatures are presented.
