The nontrivial ``cooperative'' behavior of the Stokes component of light transmitted through the medium is proven to be completely determined by the interference of scattering amplitudes in different sub-channels of the Stokes channel, which obviously combines all the sub-channels with an odd number of photon conversions. The theory of superfluorescence is then derived as the limiting case of the SRS theory.RevTex, 5 pagesQuantum PhysicsCondensed MatterQuantum Interference Mechanism of Cooperative Optical Phenomena in Extended Mediatext
