| Abstract: | The combustion driven CO2 gasdynamic laser(GDL) is similar with advanced aero-engine.The possibility of refitting a CO2 GDL from an aero-engine was discussed here,then the conception,basic frame and key techniques were analyzed.A nozzle figure was designed in allusion to the typical working condition of aero-engine,small signal gain and flow field distribution were calculated primarily.The result that high small signal gain is achieved shows that CO2 GDL based on the turbojet is possible. |
