Fifteen new, Raman far-infrared (FIR) laser emission lines in CH/sub 3/F have been excited by optically pumping up to 24 GHz off resonance with high-intensity CO/sub 2/ TEA laser radiation (up to 20 MW/cm/sup 2/). Most of these new lines are produced with high quantum efficiency in a waveguide laser system. High-intensity laser pumping could also be applied to other gases of produce many new, efficient lines. The present results suggest that a nearly continuously tunable source of FIR radiation in the 175--500-..mu..m range could be obtained through Raman laser emission in CH/sub 3/F using a tunable, multiatmospheric CO/sub 2/ pump laser.
