概述了超短激光脉冲中时空耦合效应的研究进展。将时空耦合效应分为一阶时空耦合和高阶时空耦合两大类,并详细介绍了两类时空耦合效应的研究历史和现状。其中一阶时空耦合效应相对较为简单,对其的理论及实验研究也较为充分。相比一阶时空耦合效应,高阶时空耦合效应的起源更广泛、种类更丰富、时空结构更复杂。目前,对高阶时空耦合效应的研究也刚处于起步阶段。最后,展望了该领域的研究趋势。
The research progress of the spatio-temporal coupling effect in ultrashort laser pulses is summarized. The space-time coupling effect is divided into two categories: first-order spatio-temporal coupling and high-order spatio-temporal coupling, and the history and current status of the two kinds of spatio-temporal coupling effects are introduced in detail. One of the first spatio-temporal coupling effect is relatively simple, its theoretical and experimental study is also more adequate. Compared to the first-order spatio-temporal coupling effect, high-order spatio-temporal coupling has its origins more extensively, more abundant species and more complex space-time structure. At present, the research on the high-order spatio-temporal coupling effect has just begun. Finally, the research trend in this area is prospected.
