Generalized with respect to the Stark interaction of atoms with a vacuumfield of zero photon density, Dicke's model is used to describe the Ramansuperradiance of a localized ensemble of identical atoms in a coherentnon-resonant light wave. It is shown that at a certain critical number of atomsin the ensemble the stabilization effect of the excited state of the ensemblerelative to collective atomic decay is possible, with superradiance of theatomic ensemble being suppressed. When the number of atoms is close to thecritical value, superradiance exhibits features that are opposite to theeffects of the conventional superradiance in the pulse delay time. Theidentified features depend on the intensity of an external coherent field aswell as make it possible to assess whether the Stark interaction of an ensemblewith a photon-free vacuum electromagnetic field is significant or not.
