Efficient chemical oxygen – iodine laser with a high total pressure of the active medium

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 O₂(¹Δ) oxygen, and vertical arrays of cylindrical nozzles to inject the N₂ – I₂ mixture between the first two streams. For a molar chlorine flow rate of 39.2 mmol s^-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.
