Abstract

A gasdynamic laser of premixing type fueled with benzene (C6H6) and nitrous oxide (N2O) was developed, using which the small-signal gain characteristics were studied. Also, comparisons of performance were made between nozzles of two-dimensional type and of three-dimensional screen type. With two-dimensional nozzle, the small-signal gain proved to rise sensitively with increasing combustion temperature, to reach 0.65 m-1 at 2,400 K. With screen nozzle, the temperature dependence of small-signal gain was similar in trend. The level of small-signal gain, however, proved to be roughly 0.3 m-1 higher with two-dimensional than with screen nozzle.
