In this Letter, we introduce a new class of abruptly autofocued and rotated circular chirp Pearcey Gaussian vortex beams (AARCCPGVBs) which tend to abruptly autofocused circular chirp Pearcey vortex beams or chirp Gaussian vortex beams by adjusting the spatial distribution factors. Different from other rotated beams [Opt. Lett. 31, 694 (2006) [CrossRef] and Opt. Lett. 31, 2199 (2006) [CrossRef] ], the AARCCPGVBs are autofocused abruptly, maintain a low rotating speed before the focal point, and rotate abruptly and quickly in the focal point. Further, the position of the focal point in the propagating direction can also be controlled by adjusting the chirp factor.

突然自动聚焦和旋转的圆形rpPearcey高斯涡旋光束

在这封信中，我们介绍了一类新型的突然自聚焦和旋转的圆形rp Pearcey高斯涡旋光束（AARCCPGVB），它们倾向于通过调整空间分布因子来自动聚焦圆形chi Pearcey涡旋光束或chi高斯涡旋光束。与其他旋转光束不同 来吧 31，694（2006）[交叉引用] 和选项。来吧 31，2199（2006）[交叉引用] ]时，AARCCPGVBs被突然自动聚焦，维持低的焦点之前旋转速度，并且在焦点处突然和快速旋转。此外，还可以通过调整线性调频因子来控制焦点在传播方向上的位置。
