Superradiant amplification in an optically dense three-level cascade system

We study superradiant amplification in a pressure-broadened three-level cascade system. The effects of the system initial coherence, degree of atomic inversion, and the length of the sample on the spatio-temporal distributions of the emitted fields from the upper and lower transitions are computed for a slab geometry.
