The mixing electric-discharge gasdynamic laser - A unique device for investigating energy transfer laser systems
Abstract
A number of laser systems have been investigated in an electric-discharge gasdynamic laser in which mixing in the supersonic region is employed. These systems are generated by vibrational energy transfer from the discharge-excited species to the injected species. This technique allows preferential excitation of molecules which are not specifically excited by electron impact. Energy transfer from CO, N2, H2, and D2 has been found to lead to CW laser systems in either CO2, N2O, CS2, or C2H2. The relative efficiencies of these systems suggest that resonant energy transfer is important. The CW lasers resulting from energy transfer from CO to C2H2 and CS2 are discussed, and the status of the pulsed CO2 laser at 14 or 16 microns is reviewed.
