Novel Concepts for Chemical Oxygen Iodine Lasers

In this Phase II proposal Physical Sciences Inc. (PSI) describes a program to develop and demonstrate a novel class of chemical oxygen iodine lasers (COIL) that would eliminate the need for consuming the singlet oxygen energy source to produce atomiciodine. Our concept would also allow the iodine "fuel" to be premixed with the singlet oxygen. This may eliminate the present requirement for fine scale, molecular iodine mixing nozzles and injectors. It also offers the opportunity for pulsed COILoperation since the atomic iodine can be produced on demand. Using several analytical tools and experimental results developed in the Phase I program, we propose to design, build, test and install key modules on an existing Air Force Research LaboratoryCOIL device. Our overall Phase II objective is to demonstrate and characterize our premixed concept on a realistic COIL being used to develop advanced devices for military applications.
