摘要

我们描述了一系列具有有限能量和时空平滑振幅的准轴向和准单色光波包，这些波包在时空聚焦时会产生一个奇异的强度，即一个会聚的球形波面和一个负的时空啁啾。理想聚焦时的这种奇异行为在实际聚焦中表现为有限孔径，在具有高阶色散的介质中表现为 "爆炸 "行为，其特点是在打开孔径半径时，能量会无限增加，从而对聚焦强度和时空分辨率进行持续控制。这些波包提供了一种新的聚焦方式，在聚焦强度和分辨率方面优于标准高斯波包，为能量集中及其控制至关重要的应用提供了新的可能性。

Three-Dimensional Exploding Light Wave Packets

We describe a family of paraxial and quasi-monochromatic optical wave packets with finite energy and smoothly shaped amplitude in space and time that develops a singularity in the intensity when spatio-temporally focused by imparting a converging spherical wavefront and a negative temporal chirp. This singular behavior upon ideal focusing is manifested in actual focusing with finite apertures and in media with high-order dispersion with “exploding” behavior featuring an indefinitely increasing concentration of the energy when opening the aperture radius, thus exercising continuous control on the focal intensity and spatial and temporal resolution. These wave packets offer a new way of focusing that outperforms what can be achieved with standard Gaussian wave packets in terms of focal intensity and resolution, providing new possibilities in applications where energy concentration and its control are crucial.

期刊介绍： Photonics (ISSN 2304-6732) aims at a fast turn around time for peer-reviewing manuscripts and producing accepted articles. The online-only and open access nature of the journal will allow for a speedy and wide circulation of your research as well as review articles. We aim at establishing Photonics as a leading venue for publishing high impact fundamental research but also applications of optics and photonics. The journal particularly welcomes both theoretical (simulation) and experimental research. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files and software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
