Abstract

Experimental observation of simultaneous oscillation at the Raman frequency and a cascade frequency in a broadly tunable¹³CH3F far-infrared laser is reported. Oscillation on both components persists over the full 25 GHz separation between the $v_{3}R(36)$ and $R(37)$ lines. This observation is in marked contrast to the behavior of the tunable¹²CH3F 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.
