We theoretically and experimentally study the propagation characteristics of elliptical Airy vortex beams (EAVBs) with a circular concentric vortex. It is found that EAVBs inherit the abruptly autofocusing properties of the circular Airy beams (CABs), but EAVBs will have a better autofocusing performance than circular Airy vortex beams (CAVBs) under certain conditions. It is also found that the initial $m$-order concentric vortex of EAVBs splits into $|m|$ first-order vortices at the autofocusing plane, and the focusing pattern splits into $|m| + 1$ bright spots with the pattern’s tilting direction related to the sign of $m$ [$m$ is the topological charge (TC) of the vortex]. These characteristics of EAVBs may have potential applications in TC detection, optical micromanipulation, communications, and other fields.

圆形同心涡椭圆通风光束的特性及其实现。

我们在理论上和实验上研究具有同心圆圆形椭圆椭圆形涡旋光束（EAVB）的传播特性。已经发现，EAVB继承了圆形艾里光束（CAB）的突然自动聚焦特性，但是在某些条件下，EAVB会比圆形艾里涡流光束（CAVB）具有更好的自动聚焦性能。还发现，EAVB的初始$ m $阶同心涡旋在自动聚焦平面处分裂为$ | m | $一阶涡旋，聚焦图案分裂为$ | m |。+ 1 $个亮点，其倾斜方向与$ m $ [ $ m $的符号有关是涡旋的拓扑电荷（TC）]。EAVB的这些特性可能在TC检测，光学显微操作，通信和其他领域中具有潜在的应用。
