Abstract
The occurrence of superradiance in the far infrared has been extended to the homogeneously broadened regime with the observation of delayed single-pulse emission in methyl fluoride at 496 μm. The delay, width, intensity, and asymmetry of the observed pulses are compared with the predictions of several theoretical models. Reasonable quantitative agreement is found with a Maxwell-Bloch mean-field model and a Maxwell-Bloch model including unidirectional propagation. The relation of the observations to steadystate superradiance and the contraction of the emitted pulse is discussed.

Although the FIR is not completely polarized, the other componentof polarization will be trapped by multiple reflectionand absorption, and will not continue to feedback. Theinfluence of introduced feedback has been observed, allowingus to claim that the feedback in our experiment wasnegligible.

This density corresponds to an excitation of 14.2% of theavailable ground state population. This is only slightlyless than the theoretical maximum of 16.7% for a linearly polarized pump.

Re will be a factor of 10 larger than its normal thermal value due to the population trapping effect discussed earlier.

In these experiments, only 5% of the initially excited molecules contribute to the pulse due to the fact that the pulse delays are ∿ 3 T1. However, because of the geometric scaling behavior of Ts, under the appropriate conditions damping becomes sufficiently small to allow nearly full extraction of the initial excitation energy even in the non-steady state regime; see Eq. (19) and the discussion following.
