Micro- and nanostructured surfaces of materials of different kinds represent the building blocks of many technologies from tribology and anti-freezing applications to energy harvesting, sensing, tribology, marking, and biomedicine. Femtosecond laser irradiation of various materials allows to perform modification of surface properties with ultra-high precision. Achieving surface structuring with high reproducibility, homogeneity, and regularity is still an essential topic in the investigations related to large-area texturing of surfaces.
In our research, we focus on understanding the mechanisms of laser surface structuring and optimization of the ultrashort laser irradiation conditions toward faster, cheaper, and more precise micromachining of surfaces of materials of different kinds. Our studies include laser-induced periodic surface structures (LIPSS) and more sophisticated surface morphologies like achieving high-precision craters/holes and specific surface functionalities.
