Abstract: Intense waves, subject to a parametric exchange of energy in dispersive media may spontaneously emit radiation at new frequencies. This effect represents a spatially dynamic version of parametric fluorescence with a single pump beam. Enhancement of the scattering into new frequencies is predicted near homoclinic or separatrix evolutions of the continuous-wave parametric processes. Examples of the decay of the coupled waves are given for three- and four-photon interactions.
