A Link Between Quantum- and Semi-Classical Theories for Super-Radiance via an Unrestricted Markovian Model
For the past few years many superfluorescence experiments have been realized in the infrared (or near infrared) frequency range for pencil-shaped samples [1–5]. In the two opposite directions the experiments exhibit the emission of an intense radiation after a considerable delay with respect to the characteristic superradiant time TR (about a hundred τR). These two radiations consist, in general, of several successive pulses with decreasing intensities, or ringings [1,3] (the single-pulse superfluorescence in Cesium  will be discussed later).

- 9.R. Bonifacio and co-workers have recently shown that the mean-field theory may be valid in some limiting cases, particularly in the limiting case of single-pulse superfluorescence (See their communication in the proceedings of the Fourth Rochester Conference on Coherence and Quantum Optics, June 1977, this volume, p. 939).Google Scholar
