Surface nanostructuring enables the manipulation of many essential surface properties. With the recent rapid advancements in laser technology, a contactless large‐area processing at rates of up to m2 s−1 becomes feasible that allows new industrial applications in medicine, optics, tribology, biology, etc. On the other hand, the last two decades enable extremely successful and intense research in the field of so‐called laser‐induced periodic surface structures (LIPSS, ripples). Different types of these structures featuring periods of hundreds of nanometers only—far beyond the optical diffraction limit—up to several micrometers are easily manufactured in a single‐step process and can be widely controlled by a proper choice of the laser processing conditions. From a theoretical point of view, however, a vivid and very controversial debate emerges, whether LIPSS originate from electromagnetic effects or are caused by matter reorganization. This article aims to close a gap in the available literature on LIPSS by reviewing the currently existent theories of LIPSS along with their numerical implementations and by providing a comparison and critical assessment of these approaches.

麦克斯韦与马兰戈尼会面-关于激光诱导的周期性表面结构的理论综述

表面纳米结构能够控制许多基本的表面性能。随着激光技术的最新飞速发展,非接触大面积加工的速率高达m 2 s -1另一方面,近二十年来,在所谓的激光诱导的周期性表面结构(LIPSS,波纹)领域,我们取得了极为成功和深入的研究,从而在医学,光学,摩擦学,生物学等领域实现了新的工业应用。 )。不同类型的这些结构设有数百纳米仅-远远超出期间的光学衍射极限高达几微米容易地以单步工艺制造,并且可以通过激光加工条件的适当选择来广泛控制。然而,从理论的角度来看,关于LIPSS是源自电磁效应还是由物质重组引起的争论,引起了激烈而又充满争议的争论。
