Coherent Scattering of an Electromagnetic Wave in a Nanodisperse Medium with Induced Redistribution of Nanoparticles in an Additional Light Field

It is shown that a specific nonlinear collective photon–photon interaction occurs in a nanodispersed medium, which corresponds to the transition of the medium in an intense electromagnetic field to an optically dense state, and which in its physical sense can be called the induced coherent interaction of laser fields.
