摘要
In the 10-kW chemical oxygen-iodine laser (COIL) of DLR, the small signal gain and the laser output power were measured for identical gas now conditions. The comparison of both results is used to elaborate the expressiveness of small signal gain for COIL laser design. For these investigations the temporal and spatial dependencies of small signal gain and laser power are measured along the flow axis of the cavity. The measurement of small signal gain is performed try a commercial diagnostic system of PSI with a software package upgraded by the Air Force Research Lab of Kirtland, U.S.A (1,2,3,4) The laser power is extracted in a stable resonator configuration. In case of spatially resolved investigations, slit apertures of 6 mm width in flow direction are integrated in the cavity.
