Abstract : A gas dynamic laser having high temperature high pressure gas produced from combustion is expanded in a first nozzle to provide a population inversion in a first cavity from which laser energy is extracted. The gas is then passed through oblique shocks to compress the gas slightly after which heat is added to obtain major compression. The gas is then expanded in a second nozzle structure to provide a population inversion in a second cavity from which laser energy is extracted. The gas is again passed through oblique shocks to decelerate the flow slightly after which the gas is passed through a subsonic diffuser for release to the atmosphere.
