Paper Abstract

An advanced Chemical Oxygen-Iodine Laser (COIL) using the chemical generation of atomic iodine was studied. Atomic iodine is produced by the reaction of atomic chlorine with hydrogen iodide (HI) in two separated reactors tightly attached to the supersonic laser cavity. The iodine-contained mixture is injected to the flow of singlet oxygen by means of the supersonic orifices located 5 mm downstream the nozzle throat. The atomic iodine number density in the laser cavity up to 1.2 x 1015 cm-3 and a small-signal gain up to 0.35 %/cm were achieved. An rather high quenching of singlet oxygen by HI caused that the attained laser power was low. The results of small signal gain and the laser power are compared with the previous system including the mixing of reactants upstream the nozzle throat.
