| Abstract: | The study of the propagation properties of Pearcey-Gaussian beams in photorefractive media is essential for understanding the dynamics of special beams. However, the specific effects of different parameters, such as the truncation factor, chirp factor, refractive coefficient, and beam spacing, on the propagation properties of a single Pearcey-Gaussian beam and the interactions between two Pearcey-Gaussian beams need to be clarified. This paper analyzes the dynamical properties of Pearcey-Gaussian beams and their interactions using a stepwise Fourier method. The results show that the truncation factor regulates the intensity distribution of the optical field, the initial chirp factor controls the deflection direction, and the refractive coefficient modulates the spatial soliton respiration period of a single beam. In a double-beam setup, the refractive coefficient and beam spacing affect the repulsive force, while the chirp factor alters the number of solitons. This study provides a theoretical basis for understanding the exceptional beam propagation dynamics. [ABSTRACT FROM AUTHOR] |
