Abstract
A new type mist singlet oxygen generator (Mist-SOG) for the chemical oxygen-iodine laser (COIL) has been developed. This SOG is devoted to make the liquid recirculation unnecessary with the complete reaction through a single pass of basic hydrogen peroxide (BHP). In order to determine the quantity of water vapor, a gas sampling system has been introduced newly. In this experiment, 43% of Cl2 utilization and 39% of singlet oxygen yield were obtained with Cl2 molar flow rate of 4.7mmol/s. H2O2 utilization in the BHP was achieved as high as 9.6%.
