Abstract
Chemical oxygen-iodine laser (COIL) having a wavelength of 1.315 μm 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° to avoid the problem of carry over of droplets, which is one of the major drawbacks of horizontal systems. The system has been operated using uncooled nitrogen as a buffer gas. The paper reports the results on the studies carried out on this COIL system. Under optimum conditions, we have been able to achieve stable and reproducible output power of 350 W for a chlorine flow rate of 22 mmol/s thus yielding a chemical efficiency of 17.5%.
