We simulate the propagation of the abruptly autofocusing chirped ring Pearcey Gaussian vortex (CRPGV) beams with caustics by modulating the phase of a circularly symmetric optical wavefront appropriately. The propagation characteristics of the CRPGV beams are explored in the Kerr medium. Different caustic surfaces of revolution which can be used as optical bottles are formed during the propagation. We also introduce the influence of the initial input power, the chirp factor and the stochastic type perturbations for the CRPGV beams during the propagation. Furthermore, the dynamics of the optical bottle and the breathers-like structures are explored in detail.
我们通过适当地调制圆对称光波前的相位,模拟了具有焦散的突然自聚焦啁啾环形皮尔斯高斯涡旋(CRPGV)光束的传播。在克尔介质中研究了CRPGV光束的传播特性。在传播过程中形成了不同的可作为光学瓶的旋转焦散面。我们还介绍了传播过程中初始输入功率、啁啾因子和随机型微扰对CRPGV光束的影响。此外,还详细研究了光学瓶和类呼吸子结构的动力学。
