Jens Oltmanns, PhD student in the department Short Pulses / Nanostructures, studies the physical principles of the formation of surface nanostructures upon irradiation with ultrashort laser pulses. He presented his results in a paper entitled: “Investigation of the plasmonic nature of laser-induced periodic surface structures” at the ” The 22nd International Symposium on Laser Precision Microfabrication (LPM2021)” of the “Japan Laser Processing Society (JLPS)”. Jens Oltmanns’ presentation was honored by the scientific committee of the conference with “The LPM 2021 Outstanding Student Paper Award (Full Oral Presentation)”.
