The favorable combination of high material removal rate and low influence on the material beneath the ultra-short pulsed laser-processed surface are of particular advantage for sample preparation. This is especially true at the micrometer scale or for the pre-preparation for a subsequent focused ion beam milling process. Specific surface features, the laser-induced periodic surface structures, are generated on femtosecond laser-irradiated surfaces in most cases, which pose an issue for surface-sensitive mechanical testing or microstructural investigations. This work strives for an approach to enhance the surface quality of glancing-incident laser-processed surfaces on the model material copper with two distinctly different grain sizes. A new generalized perspective is presented, in which optimized parameter selection serves to counteract the formation of the laser-induced periodic surface structures, enabling, for example, grain orientation mapping directly on femtosecond laser processed surfaces.

超短脉冲激光加工表面具有高材料去除率和对其下方材料影响小的良好组合，这对于样品制备具有特别的优势。在微米尺度或后续聚焦离子束铣削工艺的预制备中尤其如此。在大多数情况下，飞秒激光辐照表面会产生特定的表面特征，即激光诱导的周期性表面结构，这给表面敏感的力学测试或微观结构研究带来了问题。这项工作致力于一种方法，以提高在具有两种截然不同晶粒尺寸的模型材料铜上掠入射激光加工表面的质量。提出了一种新的广义观点，其中优化参数选择有助于抵消激光诱导的周期性表面结构的形成，例如能够直接在飞秒激光加工表面上进行晶粒取向映射。
