Abstract

Abstract In the present paper we describe a new effect - “down-conversion” of wave energy due to a nonlinear amplification of low-frequency nonresonant ion sound oscillations by beam-excited high-frequency resonant Langmuir waves. A comparison of our down-conversion's efficiency with those of decays and scattering providing ion sound generation is presented.
