Year: 1988
Type: article
Abstract: Basic study of CO\_2_ gasdynamic laser (GDL) was carried out by a conventional pressure driven shock tube equipped with a supersonic nozzle section. Population inversion of the vibrational levels of CO\_2_ in an expanding flow of mixture produced by high temperature reaction of CO-N\_2_O-H\_2\ system behind a shock wave was observed by measuring 10.6\mu\m small-single-gain. The experimental date were compared with those obtained by computer simulation assuming quasi-one-dimensional steady flow in the nozzle and three vibrational mode model. As a reservoir condition in the simulation, kinetics of Co\_2_ formation in CO-N\_2_O-H\_2\ system behind the reflected shock wave was discussed.
