Abstract In this work, we introduce a new class of light beam, the circular symmetric Airy beam (CSAB), which arises from the extensions of the one dimensional (1D) spectrum of Airy beam from rectangular coordinates to cylindrical ones. The CSAB propagates at initial stages with a single central lobe that autofocuses and then defocuses into the multi-ring structure. Then, these multi-ring perform the outward accelerations during the propagation. That means the CSAB may have the inverse propagation of the abruptly autofocusing Airy beam. Besides, the propagation features of the circular symmetric Airy vortex beam (CSAVB) also have been investigated briefly. Our results may offer a new tool for optical tweezers systems and the autofocusing as well as the self-healing properties of CSAB may be useful in optical treatment and optical communication.

圆对称艾里光束

摘要 在这项工作中，我们引入了一类新的光束，圆形对称艾里光束 (CSAB)，它是由艾里光束的一维 (1D) 光谱从直角坐标扩展到圆柱坐标而产生的。CSAB 在初始阶段以单个中央瓣传播，该瓣自动聚焦，然后散焦到多环结构中。然后，这些多环在传播过程中执行向外加速。这意味着 CSAB 可能具有突然自动聚焦的艾里光束的反向传播。此外，还简要研究了圆形对称艾里涡旋光束（CSAVB）的传播特性。我们的结果可能为光镊系统提供一种新工具，CSAB 的自动聚焦和自愈特性可能在光学治疗和光通信中有用。
