Abstract:

Not Available The intent of this research is to develop an advanced nozzle for mixing and reacting iodine (I (sub 2) or I) and singlet-delta oxygen [O (sub 2) ((sup 1) increment)] flows in COIL devices. The ultimate goal is to develop a more efficient COIL. Specific avenues for the proposed research are: (1) Current COIL nozzles typically inject a mixture of diluent gas and molecular iodine into the subsonic region of the O (sub 2) ((sup 1) increment) flow upstream of the nozzle throat. The resulting mixing leads non-uniform loading on the laser mirrors and to a non-uniform gain distribution ('sugar-scooping'). 'Tuning' the mixing and chemical reactions with an improved nozzle design may solve this problem and may also yield higher laser efficiency. (2) In the COIL mixing process, a significant amount of the energy stored in the singlet-delta oxygen is required to dissociate the molecular iodine to atoms. Analysis indicates that 4-6 O (sub 2) ((sup1) increment) molecules are required per I (sub 2) molecule. Injection of atomic iodine may result in an overall more efficient COIL system. (3) Heat release in the flow, both in the laser and due to deactivation of excited species, has a deleterious effect on laser performance, as well as on pressure recovery. An improved supersonic nozzle will mitigate this effect.
