Mode Coupling of Modulational Instabilities.

Abstract

A general formalism is developed to describe the nonlinear evolution associated with the parametric decay of an intense, coherent electromagnetic wave into an electrostatic wave, its second harmonic, and scattered electromagnetic waves in a homogeneous plasma. The effects of pump depletion are neglected and it is assumed that all waves are coherent. Two classes of solutions are found. One class is explosively unstable, while the other consists of growing aperiodic oscillations. The evolution of modulational modes is discussed. (Author)
