Abstract:
The technique for the multifrequency laser diagnostics of a vibrational nonequilibrium gas media containing CO2 molecules with the use of the unsaturated gains at the lines of the 0001–[1000, 0200]I, II and 0002–[1001, 0201]I, II transitions is presented. The influences of accuracy of gain measurements and a number of sensed lines on the accuracy of the level population and temperature determination are studied.
Keywords:
vibrational nonequilibrium gas media, CO2 molecules, multifrequency probing, level population, gas temperature
