超短激光脉冲中时空耦合效应的研究进展

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。

Research Progress of Spatio-Temporal Couplings in Ultrashort Laser Pulses

The research progress of spatio-temporal couplings in ultrashort laser pulse is summarized. The spatio-temporal couplings are classified into two categories, first order spatio-temporal couplings and high-order spatio-temporal couplings. The history and the recent situation of the study on the two types of spatio-temporal couplings are introduced. Comparing with high-order spatio-temporal couplings, the first order spatio-temporal couplings are relatively simple, and the theoretical and experimental research about them are comparatively abundant. Comparing with first order spatio-temporal couplings, the high-order spatio-temporal couplings have broader origin, more rich species and more complex space-time structure. At present, the research on the high-order spatio-temporal couplings is just in a fledging period. Finally, the research trend in this field is forecasted.
