摘要

The propagation dynamics of the circular Pearcey-Airy beam (CPAB) through the Kerr medium are first simulated, revealing various fascinating properties. In this paper, we find that the focus distance, focal position, and optical forces of the CPAB can be changed by adjusting the initial input power and chirp factors. Meanwhile, we discuss the gradient force and scattering force at the focal point of the beam. In addition, we introduce a diamond-shaped Pearcey-Airy beam (DPAB), and an analysis of the Poynting vector for the DPAB is conducted. Our study enhances the comprehension of the transmission properties of the CPAB and offers new perspectives and theoretical foundations for achieving more efficient and precise control of the CPAB in the nonlinear Kerr medium.
