The Effect of the Reaction Rates on the Gain and Power of CO2-N2 Gasdynamic Laser in the Presence of H2 and H2O)

摘要

An experimental and theoretical investigation of the effects of the chemical reactions due to H2 in the stagnation region on the CO2 - N2 gas dynamic laser performance is presented. As the rate of H2O production depends on the stagnation conditions, it is found that for stagnation temperature of about 1550 K this rate is such that the water production is negligible during the available test time in the shock tube. It is found that the small signal gain in a nozzle flow can be used for evaluation of the energy transfer rates for CO2 laser action. (Author)
