FIELD: quantum electronics; process oxygen-iodine lasers. SUBSTANCE: laser has cylindrical optical pan, nozzle assembly for creating supersonic gas flow along pan axis, and optical resonator mirror. Nozzle assembly is made in the form of conical annular supersonic nozzle mounted on side surface of pan; generating line of nozzle cone and optical axis of pan form angle at which Mach number of flow reduces in optical pan by not more than 20% compared with Mach number at nozzle outlet. In addition, laser is provided with device creating swirling flow about center line of nozzle installed at inlet of nozzle assembly, injector placed between nozzle assembly and flow swirling device, and hollow cylindrical spacers fitted between optical pan and resonator mirrors which have ducts communicating with mirror-shielding gas source. Channels are tangential to generating surface of cylindrical spacers. EFFECT: improved efficiency and service life of laser. 5 cl, 5 dwg
