A study on supersonic chemical oxygen-iodine laser with a high-performance mixing nozzle

Supersonic chemical oxygen-iodine laser (COIL) with an advanced mixing nozzle is studied. The mixing nozzle consists of a staggered arrangement of thin wedges lying across the flow duct. Its unique shape looks the letter “X” when it is viewed from the side. To use the new arrangement of iodine injector and the X-wing nozzle, 599W of output power with a chemical efficiency of 32.9% was achieved. This is the highest chemical efficiency of any supersonic COIL reported to date.
