Abstract

An effective relaxation constant for the CO2 (00v) and CO(v) vibrational levels has been experimentally obtained from measurements in the discharge. Using this relaxation constant and known excitation cross sections, a comprehensive picture of the kinetics of the CO2-He laser has been obtained. This approach does not require knowledge of the electron energy distribution function. Populations and temperatures of different vibrational levels have been calculated, as well as energy transfer rates to these levels. Quantitative results are presented and compared with otherwise known data on small-signal gain and energy transfer rates.
