A new concept of obtaining a high total pressure of the active medium of a chemical oxygen - iodine laser (OIL) is proposed and verified. The nozzle unit of the laser consists of the alternating vertical arrays of cylindrical nozzles to produce high-pressure nitrogen jets, plane slotted nozzles for the flow of O{sub 2}({sup 1{Delta}}) oxygen, and vertical arrays of cylindrical nozzles to inject the N{sub 2} - I{sub 2} mixture between the first two streams. For a molar chlorine flow rate of 39.2 mmol s{sup -1}, the output power was 700 W and the chemical efficiency was 19.7 %. The combined use of the ejector nozzle unit proposed to obtain the active medium and a super-sonic diffuser allows a significant simplification of the ejection system for the exhaust active medium of the OIL.
