Paper Abstract

A chemical method of atomic iodine generation for the chemical oxygen-iodine laser (COIL) was studied. This method is based on fast reaction of gaseous hydrogen iodide with chemically produced fluorine atoms formed by a preceding reaction of molecular fluorine with nitrogen oxide. Iodine atoms were generated in special reactors and injected into the supersonic flow of nitrogen in the COIL cavity. Concentration profiles of atomic iodine both along and perpendicular to the primary gas flow were measured in dependence on flow rates of the reaction gases. Very high concentration of atomic iodine (up to 3.2x1015 cm-3) was measured in the laser cavity with a good yield related to both F2 (up to nearly 100 %) and HI (up to 60%). An important advantage of this method is using of commercially available reactive gases. Some drawback of this method for its application in the COIL is a rather high gas temperature (250 - 400 K).
