摘要

我们报告，据我们所知，在线性非色散介质中首次观察到聚光的近轴光束。我们已经产生了这类有趣的光束，我们中的一个人最近预言了这类光束的一维和二维结构。正如我们在实验中所展示的那样，这些聚光光束显示出非常规的特征，例如像平面波一样在薄透镜的焦点上强烈聚焦的能力，同时保持其总能量有限。

Observation of concentrating paraxial beams

We report,to the best of our knowledge, the first observation of concentrating paraxial beams of light in a linear nondispersive medium. We have generated this intriguing class of light beams, recently predicted by one of us, in both one- and two-dimensional configurations. As we demonstrate in our experiments, these concentrating beams display unconventional features, such as the ability to strongly focus in the focal spot of a thin lens like a plane wave, while keeping their total energy finite.
