Commercial AISI 316L stainless steel (SS316L) surfaces are laser treated by ultraviolet 300 ps laser pulses in a laser line scanning (LLS) approach. Processing parameters are optimized (pulse energy of 2.08 µJ, pulse repetition frequency of 300 kHz, and suitable laser scan and sample displacement rates) for the generation of low spatial frequency LIPSS over a large 25 × 25 mm2 area. Different angles of incidence of the laser radiation (0°, 30°, and 45°) and different linear laser beam polarizations (s and p) produce a plethora of rippled surface morphologies at distinct grains. Scanning electron microscopy and 2D Fourier transforms, together with calculations of the optical energy deposited at the treated surfaces using Sipe's first‐principles electromagnetic scattering theory, are used to study and analyze in detail these surface morphologies. Combined with electron backscattering diffraction, analyses allow associating site‐selectively various laser‐induced‐surface morphologies with the underlying crystalline grain orientation. Resulting grain orientation maps reveal a strong impact of the grain crystallographic orientation on LIPSS formation and point toward possible strategies, like multi‐step processes, for improving the manufacturing of LIPSS and their areal coverage of polycrystalline technical materials. info:eu-repo/grantAgreement/ES/DGA/T54-23R info:eu-repo/grantAgreement/ES/MICINN/AEI/PID2020-113034RB-I00 info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 10.0 2024 OPTICS 10 / 125 = 0.08 2024 Q1 T1 PHYSICS, CONDENSED MATTER 9 / 80 = 0.112 2024 Q1 T1 PHYSICS, APPLIED 19 / 187 = 0.102 2024 Q1 T1 2.679 2024 Atomic and Molecular Physics, and Optics 2024 Q1 Electronic, Optical and Magnetic Materials 2024 Q1 Condensed Matter Physics 2024 Q1 15.1 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Martínez, Elena (orcid)0000-0003-4839-5286 Frechilla, Alejandro Universidad de Zaragoza Castro, Miguel Universidad de Zaragoza (orcid)0000-0002-9687-4903 de la Fuente, Germán Francisco (orcid)0000-0002-0500-1745 Bonse, Jörn Angurel, Luis Alberto Universidad de Zaragoza (orcid)0000-0001-5685-2366 5001 065 Universidad de Zaragoza Dpto.
