Experimental results obtained at study of inhomogeneous plasma parametric decay instabilities driven by frequency modulated pump are presented. Three-wave nonlinear dynamic system is considered by the methods of nonlinear dynamic system theory. The suppression of forward scattering instability and forced switching between two different parametric scattering regimes was observed at harmonic pump frequency modulation in dependence of modulation frequency.
Key words: parametric instability, frequency modulation, nonlinear three-wave system
