Supersonic Chemical Oxy-iodine Laser has been developed using a Singlet Oxygen Generator (SOG) with a novel approach. Generated singlet oxygen is taken out of the SOG at an angle of 40 o to avoid the problem of carry over of droplets, which is one of the major drawbacks of horizontal system. The system has been operated up to 22mmol/s chlorine flow rates. Chlorine utilization and singlet oxygen observed have been more than 90% and 60%, respectively. The observed maximum output power was 350W, thus yielding a chemical efficiency of 17.5%.
