Abstract

A multi-kilowatt supersonic chemical oxygen iodine laser (COIL) has been constructed. Two types of jet singlet oxygen generator (SOG) such as tube-array and plate have been tested. An output power of 8.8KW with chemical efficiency of 2 1 .4% was obtained at the chlorine flow rate of 45Ommole/s. The influence of BHP (basic hydrogen peroxide) temperature on the output power of COIL has been studied. And the absolute concentration of O2(1Æ) in the jet SOG was measured using the Piston-source method.
