Nonlinear Transformation of Emission into Plasma Waves,
Abstract
As a result of analysis and the solution of a nonlinear integral equation the steady-state spectral distribution and the electric field intensity of high-frequency plasma waves (plasmons), parametrically stimulated by a powerful nonpotential pumping wave in a homogeneous isotropic plasma at a pumping field frequency close to double that of the Langmuir electron frequency were found. The induced scattering of plasma waves by ions and the nonlinear shift in plasma wave frequency are the nonlinear mechanisms for noise level saturation, which lead a primarily parametrically unstable plasma to a steady-state turbulent state. The coefficient of nonlinear transformation of pumping emission energy into plasma waves attains magnitudes of the order of unity at slight exceedings of the threshold value pumping fluxes. (Author)
