FIELD: laser engineering.
SUBSTANCE: invention is related to laser equipment. Gas-dynamic channel of supersonic chemical laser consists of series-connected: laser gas generator 1, nozzle unit mixer 2, laser chamber (LC) 3 with resonator cavity and pressure recovery system, which comprises active diffuser (AD) 5 and ejector 7. Diffuser comprises passive part with pylons, located inside it, and active part, which comprises nozzle unit and mixing chamber. Low-pressure laser gas, which is already subsonic at passive part outlet, is ejected from LC 3 with supersonic jets of high pressure gas from nozzles of pylons and nozzle unit.
EFFECT: technical result consists in stabilization of parameters of laser gas flow and improved optical quality of laser gas flow.
