Abstract:
The problem of scaling chemical oxygen — iodine lasers (COILs) is discussed. The results of experimental study of a twisted-aerosol singlet oxygen generator meeting the COIL scalability requirements are presented. The energy characteristics of a supersonic COIL with singlet oxygen and iodine mixing in parallel flows are also experimentally studied. The output power of ~7.5 kW, corresponding to a specific power of 230 W cm-2, is achieved. The maximum chemical efficiency of the COIL is ~30 %.
