Ejector Chemical Oxygen–Iodine Laser with Supersonic Nozzle Bank Based on a Trip-Jet Mixing System

Nozzle banks for an ejector chemical oxygen–iodine laser consisting of two-dimensional slit nozzles with a trip-jet mixing system were tested in the cold- and hot-flow operation regimes. Horizontal Pitot scan experiments demonstrated that the mixing ability of the trips is excellent. The Mach number of the mixed flow was approximately 3. Gain measurements were conducted, and the results of these measurements revealed that the maximum gain was approximately 0.54 m-1. The gain cut off length exceeded 200 mm. Lasing experiments were also conducted, and the power was approximately 3 kW at a chemical efficiency of approximately 18%.
