description: All data and figures in the article were simulated by Matlab. The numerical method employed combines the classical spectral method in the temporal domain and the adaptive step size Runge Kutta method in the spatial domain. Herein, we provide all Matlab data and related graph source files for figures 1-6 in the article. This dataset is divided into the following two files. The 'data' file is the Matlab data for Figures 1-6, and the other file is the Matlab source file for Figures 1-6. In the ‘data' file, six files named fig1 (2, 3, 4, 5, 6) were created in the order of the figures, corresponding to the data in figures 1-6. The six files fig1 (2,3,4,5,6) are still named in the other file, according to the order of the figures, corresponding to the source files of figures 1-6. The normalization parameters of Figure 1 are plane wave amplitude A0=1, perturbation frequency Omega=1.5, phase difference(between perturbation signal and pump) phi0=0.5pi, perturbation amplitudes (from top to bottom) delta=0.01, 0.1, and 0.25, respectively. The normalization parameters in Figure 2 are plane wave amplitude A0=1, perturbation frequency Omega=2, phase difference(between perturbation signal and pump) phi0=0.5pi, perturbation amplitudes (from top to bottom) delta=0.01, 0.25, and 0.5, respectively. The normalization parameter in Figure 3 is the plane wave amplitude A0=1, and phase difference(between perturbation signal and pump) of phi0=0.5pi and 0.3pi, respectively. The normalization parameters in Figure 4 are plane wave amplitude A0=1, disturbance frequency Omega=1.5, disturbance amplitude delta=0.1, and the phase difference between the disturbance signal and the pump light (from top to bottom) of phi0=0.1pi, 0.3pi, and 0.5pi, respectively. The normalization parameter in Figure 5 is the plane wave amplitude A0=1, and the perturbation amplitudes are delta=0.1 and 0.01, respectively. The normalization parameters in Figure 6 are plane wave amplitude A0=1, disturbance frequency Omega=2.2, disturbance amplitude delta=0.25, and the phase difference between the disturbance signal and the pump light (from top to bottom) of phi0=0.1pi, 0.3pi, and 0.5pi, respectively.
