A chemical method of atomic iodine generation followed by iodine injection into the supersonic nozzle of Chemical Oxygen Iodine Laser (COIL) was studied experimentally. This method is based on the reaction of gaseous hydrogen iodide (or deuterium iodide) with fluorine atoms formed in a preceding reaction between molecular fluorine and nitrogen oxide. Iodine atoms were generated in specially designed reactors tightly attached to the laser body and then injected into the singlet oxygen flow in laser. Yields of atomic iodine related to either F2 or HI were rather high (I/F2100%, I/HI 60%).
