Abstract:
A theoretical analysis is made of the vibrational relaxation in a nonequilibrium stream in a gasdynamic laser utilizing CO+N2+CO2+H2O mixtures. The dependence of the population inversion for the 0001–1000 transition in the CO2 molecule on the concentration of CO is obtained. It is shown that under certain conditions it should be possible to construct a gasdynamic laser utilizing CO2 transitions in nitrogen-free mixtures.
