1975 R. Bonifacio & L. A. Lugiato in Physical Rev. A. 11 1507/2 The system spontaneously creates correlations, i.e., a macroscopic dipole which gives rise to a pulse whose maximum intensity is proportional to N2 and whose time duration is proportional to N−1. We call this phenomenon superfluorescence.
1980 Nature 8 May 70/1 Superfluorescence produces radiation pulses which have much larger amplitudes than those which one would obtain in normal incoherent atomic radiation processes.
1998 Polymer 39 3656/2 The independence of the fluorescence lifetime on multiple excitation of polymer chains indicates the absence of cooperative emission like superradiance or superfluorescence.
2005 P. W. Milonni Fast Light, Slow Light & Left-handed Light iv. 125 In the case of the optical amplifier, the quantum noise is attributable to the onset of superfluorescence.
