This paper is devoted to the study of the nonlinear interaction of waves generated by the stimulated Raman scattering with plasma in the PALS experiment. We solve problem of the influence of nonlinear interaction of plasma wave with particles on the sum of actions generated by the laser wave. Numerical value of the change of the electric field of the quasimode determined by beating of forward and backward plasma waves of Raman scattering given by trapping of plasma particles in the PALS experiment is calculated, too. Numerical values are obtained for typical parameters of the PALS experiment, but for the laser wavelength at vacuum gimel = 438 nm (no for the fundamental wavelength of the laser ASTERIX). The nonlinear effects are greater than the same effects determined by the fundamental laser wavelength.
