论文摘要
在这封信中，我们介绍了一类新的光束，即圆形对称的空气梁（CSAB），该光束是由一维（1D）光频谱从矩形坐标到圆柱形的一维（1D）频谱产生的。 CSAB在初始阶段以自动对焦，然后将其转化为多环结构。然后，这些多环在传播过程中执行外向加速度。这意味着CSAB具有突然自动化的通风梁的反向传播。此外，还详细研究了圆形对称空气涡流束（CSAVB）的传播特征。我们的结果为实用应用而突然自动凝视着通风的光束提供了一个补充工具。
In this letter, 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-rings structure. Then, these multi-rings perform the outward accelerations during the propagation. That means the CSAB has 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 in detail. Our results offer a complementary tool with respect to the abruptly autofocusing Airy beam for practical applications.
