Abstract : An oxygen-iodine laser system that includes a source of gaseous singlet delta oxygen O2(delta) and a source of gaseous iodine monochloride, ICl, that directs their respective gases to manifolds and then to a mixing reacting nozzle. The nozzle discharges the mixed gases into a lasing cavity. When mixed the ICl dissociates into atomic iodine, I, and atomic chlorine, Cl, in the presence of the excited oxygen. The atomic iodine is subsequently excited to I(2p1/2) lasing state by the excited oxygen. The lasing cavity, which includes optical means for extracting radiation, includes exhaust ports connected to an exhaust system. the advantage of using ICl in the laser rather than conventional source of atomic iodine is that for a given temperature the operating pressure of the laser can be higher without encountering efficiency reducing condensation of the iodine.
