摘　　要：随着超快超强激光技术的发展,强激光场光与物质相互作用的研究得到了广泛的关注。与此同时,光场调控技术在经典光学领域中的快速发展为光学操控提供了一个新的自由度。近年来,这两个不同领域之间的结合——具有空间结构的强激光场与物质相互作用,成为了强场物理前沿研究的热点之一。光电离和高次谐波是传统强场科学中两个十分基本又非常重要的物理过程。本文总结和综述了涡旋强激光场对光电离过程的影响和控制方面的研究进展,以及利用涡旋光束或者柱矢量光束驱动气体高次谐波产生等方面的最新工作,最后展望了具有空间结构强激光场与物质相互作用物理和光场调控研究的发展方向。With the development of ultra-fast and ultra-strong laser technology,the interaction between light and matters in the strong-field regime has been extensively studied.At the same time,the rapid development of spatial light modulation technology in classic optics provides a new degree of freedom for optical manipulation.In recent years,the combination between these two different fields,namely,driving the intense-laser-matter interaction by the spatially structured light fields,has become one of the research hotspots in strong-field science.Strong-field ionization and high-order harmonic generation are two fundamental and important physical processes in traditional strong-field community.Here,the effect of optical vortex beams in strong-field ionization and its related research progress are first introduced.Then,the latest works of gas high-order harmonic generation driven by vortex beams or cylindrical vector beams in the past decade are introduced.At last,we look ahead to the prospects of intense spatially structured laser fields in strong-field physics.
