Double and triple frequency laser outputs have been obtained with the adoption of a parallel grating-grating cavity. The results are derived at a total gas pressure of 50.7 kPa, with the gas combination in volume fraction of 13% CO2, 13% N2, 74% He under 27 kV voltage. The double or triple frequency output laser possesses fine space overlap and time synchronization, and is tunable within a wide frequency ange. The laser exports beside one of the gratings approximately parallel to the cavity axis. It can meet the requirement of some materials’ double (or multiple) frequency excitation and isotope separation.
