By pumping CH(3)F with a 150-mJ, continuously tunable, multiatmosphere CO(2) laser, we have produced approximately 0.2-mJ far-infrared laser pulses that can be tuned quasi-continuously over approximately 85% of the range from 220 to 400 microm. The tunable far-infrared laser action results from two-photon (Raman) transitions in the R branch of the CH(3)F nu(3) band.

Fifteen new, Raman far-infrared (FIR) laser emission lines in CH(3)F have been excited by optically pumping up to 24 GHz off resonance with high-intensity CO(2) TEA laser radiation (up to 20 MW/cm(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 to produce many new, efficient lines.
