Relaxation Processes and Population Inversion in a Multicomponent Plasma in a Co2 Discharge Laseretail the population inversion mechanism in a CO. laser, we must recall some fundamental information on these molecules, consider some aspects of the theory of relaxation in a mixture of molecular gases, and present briefly the available information on the CO. laser action.

This must be borne in mind in studies of the CO. laser action, i.e., in discussing the processes which ensure pumping of the upper laser level and the relaxation processes which depopulate the lower and upper laser levels.
