摘要

Laser output power characteristics of the combustion-driven CO_2 Gasdynamic Laser (CO_2GDL) are presented. Laser extraction is carried out with supersonic nozzle of circular-circular (CC) and shock free (SF), which has common Area-ratio (A/A*=20) and various expansion length (CC nozzle with expansion length of 30mm and SF nozzle of 45, 33, 20mm). In laser output power measurements, maximum power of 24.5 W is obtained at CC 20 nozzle of expansion length of 30mm, which has maximum small-signal gain of 0.5m~-1.
