Patent ID: 8141796

Claim:
An iodine injection system for injecting iodine into a chemical oxygen-iodine laser, the system comprising: a nozzle having a central axis of symmetry and pair of opposed curved walls defining an area for gas flow there between, the nozzle including: (a) an inlet defined by the pair of opposed curved walls; (b) a throat located downstream from the inlet and defined by convergence of the pair of opposed curved walls, from the inlet to a pair of opposite sharp corners, at a point of closest convergence of the opposed walls; (c) an exit nozzle portion having divergently extending portions of the pair of opposed curved walls extending from the sharp corners of the throat, the divergent extending portions of the pair of opposed walls terminating at a nozzle exit end; and at least one curved strut located within the nozzle, the curved strut upstream of an exit plane and downstream of the throat; and a plurality of orifices arrayed along the at least one curved strut, each orifice directed away from the throat of the nozzle toward the nozzle exit end and each orifice injecting iodine toward the nozzle exit end.
