Paper Abstract

The chemical oxygen-iodine laser (COIL) with a chemical method of atomic iodine generation was studied. Two methods of atomic iodine generation were proposed and developed. They are based on fast reactions of gaseous hydrogen iodide with chemically produced chlorine or fluorine atoms. Atomic iodine formation via Cl atoms we studied earlier by mixing of reaction gases directly in the primary O2(1Δg) flow in COIL. A revealed oxidation of HI by singlet oxygen and the O2(1Δg) quenching by some reaction product, however, reduced the attainable laser gain. This problem could be avoided by atomic iodine generation in separate reactors with following injection of atomic iodine into the primary O2(1Δg) flow. Gain measurements using this arrangement are presented in this paper. New experimental results on atomic iodine production via F atoms are also summarized. Using of reactive gases commercially available in pressure cylinders is the main advantage of this method.
