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 uni t of the laser consists of the alternating vertical arrays of cylindrical n ozzles to produce high-pressure nitrogen jets, plane slotted nozzles for th e flow of O-2((1)Delta) oxygen, and vertical arrays of cylindrical nozzles to inject the N-2 - I-2 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 c hemical efficiency was 19.7%, The combined use of the ejector nozzle unit p roposed to obtain the active medium and a super-sonic diffuser allows a sig nificant simplification of the exhaust active medium system of the OIL.
