Abstract:
Carbon oxide molecular gasdynamic laser with a stagnation chamber filled in which a hot pressurized gas or gas mixture and a supersonic nozzle connected to the chamber and forming a hot gas stream along which the gas is cooled due to expansion. An injector is situated near the throat of the nozzle and injects a cold gas stream coaxially into the hot stream. In the case of a CO2 molecular gasdynamic laser, the hot stream comprises nitrogen alone and the cold gas stream CO2 and a relaxant additive monoatomic gas. In the case of a CO molecular gasdynamic laser, the hot gas stream comprises a mixture of nitrogen and CO and the cold gas stream the relaxant additive monoactomic gas. The mixture of nitrogen and CO can be obtained by an exothermic chemical reaction in the stagnation chamber.
