 note = {This paper gives the results of experimental investigation of CO_2/N_2 mixing gasdynamic laser by means of synchronizing operation of two nondiaphragm shock tubes, together with the quasi-one-dimensional analysis based on instantaneous mixing assumption. By the satisfactory synchronization of shock reflections, separately heated CO_2 and N_2 are mixed to accomplish the population inversion, using two-dimensional or conical screen nozzle. The small signal gain coefficient measured was compared with the estimate by the analysis. Also the measurement of lasing power and the observation of flow field by Schlieren method were supplementarily conducted. As the results, the gain coefficient measured can be simulated qualitatively by the estimate, except for higher stagnation temperature rang of CO_2 (+He) above 1500°K. As for a fixed nozzle configuration, the existence of optimum stagnation conditions for CO_2/N_2 mixing GDL is clarified. The superiority of supersonic downstream injection by screen nozzle is also ascertained., 資料番号: SA2401436000},
