The formation and properties of laser-induced periodic surface structures (LIPSS) was investigated on different technically relevant glasses including fused silica, borosilicate glass, and soda-lime-silicate glass under irradiation of fs-laser pulses characterized by a pulse duration = 300 fs and a laser wavelength = 1025 nm. For this purpose, LIPSS were fabricated in an air environment at normal incidence with different laser peak fluence, pulse number, and repetition frequency. The generated structures were characterized by using optical microscopy, scanning electron microscopy, focused ion beam preparation and Fast-Fourier transformation. The results reveal the formation of LIPSS on all investigated glasses. LIPSS formation on soda-lime-silicate glass is determined by remarkable melt-formation as an intra-pulse effect. Differences between the different glasses concerning the appearing structures, their spatial period and their morphology were discussed based on the non-linear absorption behavior and the temperature-dependent viscosity. The findings facilitate the fabrication of tailored LIPSS-based surface structures on different technically relevant glasses that could be of particular interest for various applications.
在飞秒激光脉冲（脉冲持续时间 = 300 fs，激光波长 = 1025 nm）辐照下，研究了包括熔融石英、硼硅酸盐玻璃和钠钙硅酸盐玻璃在内的不同技术相关玻璃上激光诱导周期性表面结构（LIPSS）的形成及其特性。为此，在空气环境中以不同的激光峰值能量密度、脉冲数和重复频率，垂直入射制备了LIPSS。利用光学显微镜、扫描电子显微镜、聚焦离子束制备和快速傅里叶变换对生成的结构进行了表征。结果表明，在所有研究的玻璃上均形成了LIPSS。钠钙硅酸盐玻璃上LIPSS的形成取决于显著的熔体形成，这是一种脉冲内效应。基于非线性吸收行为和温度依赖性粘度，讨论了不同玻璃在出现的结构、空间周期及其形态方面的差异。这些发现有助于在不同技术相关玻璃上制备定制的基于LIPSS的表面结构，这对于各种应用可能具有特别的意义。
