摘要

The experimental and numerical studies for the effect of expansion length of supersonic nozzle for a combustion-driven CO_2 gasdynamic laser facility on the small-signal gain characteristics are presented. Two types of nozzle of Circular-Circular (C-C) and Shock Free (SF) with area ratio of 20 which are able to realize Mach number of 4.7 with vibrationally nonequilibrium flow are used. For C-C nozzle at expansion length of 30mm, maximum value of the small- signal gain coefficient is measured as 0.5m~-1, and also for SF nozzle at expansion length of 45, 30 and 20 mm they are 0.2 to 0.3m~-1.
