Abstract
We have found that room-temperature HF gas at millitorr pressures, optically pumped to produce a total inversion at a rotational transition in the vibrational state, emits a superradiant pulse with ringing after a considerable delay (∼ microseconds). A semiclassical analysis shows that for a high-gain system the pulse evolution is determined by a single parameter , and that inhomogeneous broadening is unimportant. Close agreement between theory and experiment is obtained.
