In the present investigation the light amplification factor of a mixtyre of 10 CO2 40 N2 50 He was measured during supersonic expansion over a wide range of variation of experimental conditions total temperature T 800-3600K, and gas pressure P 2.5-40 atm, where the relative nozzle cross-section assumed several fixed values SS 18.2, 36.2, 49 and 59, where S is the critical nozzle cross-section, and S is the cross-section in the measurement zone. A mixture of 10 CO2 90 - X N2 X H2O where X 0-5 was investigated in the total temperature range of T 800-2200K and total pressure range of P 1.5-40 atm with relative nozzle cross-section of SS 18.2, 36.2, and 59. The data obtained for the amplification factor are compared with values which were calculated by a previously proposed method.
