A method and apparatus for producing coherent radiation in CO.sub.2 vibrational-rotational transitions at wavelengths near 14 and 16 microns. This is accomplished by passing a mixture of N.sub.2 and Ar through a glow discharge producing a high vibrational temperature in the N.sub.2, passing the excited N.sub.2 through a nozzle bank creating a supersonic flow thereof, injecting the CO.sub.2 in the supersonic flow creating a population inversion in the CO.sub.2, and directing the saturating pulse of radiation near 10.6 or 9.6 microns into the excited CO.sub.2 creating a population inversion producing coherent radiation at 14 or 16 microns, respectively.
