Abstract

We have studied and explored the influence of different launch angles on the circular Pearcey beams (CPBs) without vortex or with vortex for the first time. Although launch angles can manipulate the focal length and the contrast of peak intensity of the CPBs, the shape and propagation trajectory of the CPBs maintain invariant. When the vortex is considered, the focal pattern and the contrast of peak intensity of the circular Pearcey vortex beams (CPVBs) can be changed by adjusting the magnitude of topological charges and the position of vortex. In addition, we have deliberated the propagation of the CPVBs under the action of double opposite optical vortices.

不同初始发射角圆皮尔斯涡旋光束在谐波势下的突然自聚焦特性

本文首次研究和探讨了不同发射角度对无旋涡和有旋涡圆形皮尔斯光束的影响。虽然发射角度可以影响CPBs的焦距和峰值强度对比，但CPBs的形状和传播轨迹保持不变。考虑涡旋作用时，可以通过调整拓扑电荷的大小和涡旋的位置来改变圆形皮尔斯涡旋光束的焦点模式和峰值强度的对比。此外，我们还研究了在双对角光涡旋作用下CPVBs的传播。
