Abstract
We report on the generation of widely tunable intense far-infrared radiation pulses by stimulated Raman transitions in methylfluoride gas. Using a tunable high-pressure CO2 laser we achieved, by P-branch tuning of stimulated Raman transitions in 12CH3F and 13CH3F gases, tunable generation of radiation in a series of intervals in the spectral range from 37 to 72 cm−1 covering 20% of this range. Possibilities of further extension of the tuning regions are also discussed.
