1954 R. H. Dicke in Physical Rev. 93 102/2 For want of a better term, a gas which is radiating strongly because of coherence will be called ‘super-radiant’.
1974 Sci. Amer. June 126/1 The optical gain of the rapid discharge is so large that emission becomes superradiant, which means that the unit will lase without an optical cavity.
1990 Science 9 Feb. 684/1 The PSF model in its present form completely ignores superradiant effects.
2010 Space Daily (Nexis) 20 Nov. The coherent arrangement of excitation amplitudes for the atoms in the ensembles..enhances the matter-light interaction through a phenomenon known as superradiant emission.

1968 Solid-state Electronics 11 882/2 It will be seen that the lines in the latter are broader and are more comparable to the spectrum of a diode below threshold emitting superradiantly.
1974 Sci. Amer. June 126/2 If the ultraviolet pulses are focused by a cylindrical lens to a line on the surface of the dye.., the dye will often lase superradiantly in visible light along the direction of the line.
2003 M. Csele Fund. Light Sources & Lasers iv. 105 Nitrogen-laser-pumped dye lasers frequently have enough gain to operate superradiantly as well.
