SINGLET OXYGEN GENERATOR WITH WATER VAPOR CONTROL

"Chemical oxygen iodine lasers are efficient, scalable, and have a proven ability to generate weapons class laser power. To support the future high power COIL programs, technology improvements must be realized to increase performance, efficiency, andchemical operating range, and thus more easily meet the overall system requirements, such as for the ABL EDM phase. In particular the SOG performance with mixed base BHP must be augmented to allow operation through a wider molarity range and at higher BHPtemperature to reduce magazine size and weight. Innovative methods for improving the COIL efficiency by increasing singlet oxygen output, reducing singlet oxygen losses, removing water vapor, reducing internal fluid losses and degradation, and reducingwater carryover from the SOG will further improve high power COIL performance.The proposed program will develop several innovative concepts and design an optimized SOG with a water vapor trap and other innovative features that will increase singlet oxygen and reduce water vapor at the laser cavity. Using the SOG flow/chemistry codedeveloped by STI, the innovative configurations and cold trap fluids will be developed into a first generation design and test device. Flow simulation and laser tests will be used to characterize performance, provide data to upgrade analyses andconfiguration, and verify performance of this innovative SOG hardware. The proposed program will develop a proven fir
