Effect of phase correlation on the parametric interaction of waves in a fluctuating medium

Nonlinear wave processes in a plasma with stationary random irregularities. Part II

“…In the case of three-wave interactions, the growth rate of fluctuations of the phase mismatch of waves also increases in the presence of random irregularities, which should influence the interaction characteristics. An analysis of the influence of multiple propagation in a randomly irregular layer on the thee-wave parametric interactions was performed in [21][22][23][24]. The main results of these papers are a decrease in the threshold of the decay process and a dependence of the stationary distribution of intensities on the multiplicity of propagation through the irregular layer.…”

“…The processes of three-wave parametric "frequency upshift" in the case of multiple propagation through a randomly irregular layer were considered in [21] and [23]. In the first of these papers, the twofold propagation through a layer with the reflecting boundary is analyzed in detail, and in the second one, the quasi-stationary distribution of the intensities of interacting waves is studied as a function of the multiplicity of forward propagation through similar layers.…”
