Paper Abstract

Experiments were carried out with a subsonic chemical oxygen-iodine laser (COIL), equipped with an electric discharge generator of iodine atoms. CH3I entrained in a carrier flow of Ar was used as atomic iodine precursor. About 50% of iodine contained in CH3I molecules was extracted in the generator. Up to 3.5% of electric power loaded into the discharge was spent on CH3I dissociation. A straightforward comparison of COIL performance for two cases - conventional, when I2 was injected in the singlet oxygen flow and when iodine atoms produced externally together with other discharge products were injected - was made. In the latter case nearly four times increase in output power was observed.
