Abstract
Multimode phenomena in optically-pumped lasers are studied by means of Lamb's semi-classical theory. Specifically we investigate competition between Raman and line center oscillation in off-resonantly pumped FIR lasers. The observed preference of the Raman line is shown to be the result of an inversion of the line center gain for a moderate to high intensity Raman mode.
