We report on the experimental observation of abruptly autofocusing waves. This interesting family of wave packets has been realized by using a radially symmetric Airy intensity distribution. As demonstrated in our experiments, these waves can exhibit unusual features, such as the ability to autofocus by following a parabolic trajectory toward their focus.
我们报告了对突然自聚焦波的实验观察。这种有趣的波包族是通过使用径向对称的艾里光强分布来实现的。正如我们的实验所展示的，这些波可以表现出不寻常的特性，例如能够通过沿着抛物线轨迹自动聚焦到焦点。
