超短脉冲激光诱导周期性表面结构（英文）

Laser-induced periodic surface structures with ultrashort laser pulse

激光诱导周期性表面结构(Laser-induced periodic surface structures,LIPSS)具有纳米尺度的特征结构和自重复的微观尺度的排列图案,因此,LIPSS在传感器、太阳能发电、光催化等方面具有广泛的应用前景。本文首先介绍LIPSS形成过程中超快激光与物质相互作用的复杂过程,强调瞬态光学性质和表面结构变化的作用。然后综述几种具有代表性的LIPSS形成机理,并且讨论了各自的优缺点。接着介绍了LIPSS形成过程中材料的变化,主要包括材料化学成分、晶体结构和表面微观结构的变化。最后综述了LIPSS在材料表面处理、光学和机械等方面的应用。

Laser-induced periodic surface structures( LIPSS) have a wide application prospect from sensing to solar power generation and photocatalysis mainly due to its nanoscale features and self-repetitive microscopic patterns. In this review we discuss various complex process of the interaction of ultrafast laser with matter during the formation of LIPSS,emphasizing the role of transient optical properties and surface structural changes.Then several representative LIPSS formation mechanisms are summarized and their respective advantages and disadvantages are discussed. Next,the change of materials during the formation of LIPSS is introduced,including the change of chemical composition,crystal structure and surface microstructure. Finally,the application of LIPSS in material surface treatment,optics and mechanics is reviewed.
