Mixing Gas Dynamic Lasers,
Abstract
The paper reports the results obtained with an arc-driven gas dynamic laser (GDL) having an aerodynamic nozzle designed so that cold CO2 or other gases can be injected either into the expanding N2 flow before it reaches the nozzle exit (supersonic mixing mode) or into the flow just before it reaches the nozzle throat (near-sonic mixing mode). The gases can also be premixed either before or upon injection into the plenum (GDL mode). The results obtained in the GDL mode with marginal plenum conditions are compared with those obtained in the supersonic and near-sonic mixing modes using cold CO2. Preliminary results are also given for operation in the supersonic mixing mode when a mixture of cold CS2 and He is injected into the N2 flow. The laser is described first and then the results are presented and discussed.
