Experimental observation of simultaneous oscillation at the Raman frequency and a cascade frequency in a broadly tunable /sup 13/CH/sub 3/F far-infrared laser is reported. Oscillation on both components persists over the full 25 GHz separation between the ..nu../sub 3/R(36) and R(37) lines. This observation is in marked contrast to the behavior of the tunable /sup 12/CH/sub 3/F FIR laser which produces only the Raman frequency when it is optically pumped at lower J values in the same branch. A marked qualitative difference in the large-scale emission spectra for the two lasers is also discussed.
