我们报道了对艾里光束的首次观测。这类有趣的波包最初是由贝里（Berry）和巴拉兹（Balazs）在1979年预测的，现已在一维和二维结构中实现。正如我们的实验所展示的，这些艾里光束能够呈现出一些不寻常的特性，比如在长距离传播过程中能够保持无衍射，同时在传播过程中还倾向于自由加速。
We report the first observation of Airy optical beams. This intriguing class of wave packets, initially predicted by Berry and Balazs in 1979, has been realized in both one- and two-dimensional configurations. As demonstrated in our experiments, these Airy beams can exhibit unusual features such as the ability to remain diffraction-free over long distances while they tend to freely accelerate during propagation.
