Over the past two decades, femtosecond laser-induced periodic structures (femtosecond-LIPSs) have become ubiquitous in a variety of materials, including metals, semiconductors, dielectrics, and polymers. Femtosecond-LIPSs have become a useful laser processing method, with broad prospects in adjusting material properties such as structural color, data storage, light absorption, and luminescence. This review discusses the formation mechanism of LIPSs, specifically the LIPS formation processes based on the pump-probe imaging method. The pulse shaping of a femtosecond laser in terms of the time/frequency, polarization, and spatial distribution is an efficient method for fabricating high-quality LIPSs. Various LIPS applications are also briefly introduced. The last part of this paper discusses the LIPS formation mechanism, as well as the high-efficiency and high-quality processing of LIPSs using shaped ultrafast lasers and their applications.

基于空间光调制器的飞秒激光时空干涉方法，改变800 nm飞秒激光能流密度和累积脉冲数，在316镜面不锈钢上高效率、高质量地制备了面积为5 mm×5 mm的双尺度的类鲨鱼皮肤微纳米仿生结构，并研究了该结构在不同激光照射条件下的润湿性。在激光能流密度为1.37 J/cm²，累积脉冲数为30~40的条件下，不锈钢表面碳元素含量最多增加了13.22%，润湿性由亲水（接触角88°）转变为超疏水，接触角高达165°。本研究利用灵活、高效的飞秒激光时空干涉加工方法，得到了稳定的超疏水表面，为仿生结构制备提供了新思路。
