Description
A general formalism is developed to described 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. It is assumed that all waves are coherent, and that the system is in a regime in which pump depletion may be neglected. 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
