Abstract

In the supersonic COIL the power output and the laser performance strongly depend on mixing conditions of the gas flows. For the 10 kW COIL of DLR, the effects of the gas mixing on the laser power have been experimentally investigated to work out the relations between maximum laser power and the corresponding optimum mixing conditions. For this purpose, optimally diluted iodine jets have been matched to different molar flow rates of singlet delta oxygen. These energetic considerations have been complemented by the investigation of the power dependence on fluid mechanic aspects.
