We investigate the finite power Airy beams generated by finite extent input beams such as a Gaussian beam, a uniform beam of finite extent, and an inverse Gaussian beam. Each has different propagation behavior: A finite Airy beam generated by a uniform input beam keeps its Airy profile much longer than the conventional finite Airy beam. Also, an inverse Gaussian beam generates a finite Airy beam with a good bent focusing in free space. In this paper, the analysis and experimental results of finite Airy beams are presented.
我们研究了由有限范围输入光束（如高斯光束、有限范围均匀光束和反高斯光束）产生的有限功率艾里光束。每种光束都有不同的传播特性：由均匀输入光束产生的有限艾里光束保持其艾里分布的时间比传统有限艾里光束长得多。此外，反高斯光束在自由空间中产生具有良好弯曲聚焦的有限艾里光束。本文给出了有限艾里光束的分析和实验结果。
