- Аннотация: The space and time evolution of various types of stimulated scattering of light is investigated as a function of the pump intensity for various values of the logarithmic decrement of the interacting waves. The analysis is carried out on the basis of generalized equations that are derived (with allowance for phase evolution) for the occupation numbers and fluxes of the interacting·wave quanta. It is shown that at pump intensities exceeding certain threshold values the scattered radiation intensity grows nonmonotonically, the stationary state being established in an oscillatory manner. The oscillation period depends on the pump intensity. The results are used to interpret the presence of a threshold for the modulation of intense laser radiation reflected by a plasma, which has been observed experimentally(3), and also the appearance of additional lines in the stimulated Raman-scattering spectrum [41 under sufficiently intense pump conditions.
