3D laser nanoprinting (Plenary Presentation)

11 April 2024 • 09:05 - 09:50 CEST | Auditorium Schweitzer, Niveau/Level 0


3D laser nanoprinting based on multi-photon absorption (or multi-step absorption) has become an established commercially available and widespread technology. Here, we focus on recent progress concerning increasing print speed, improving the accessible spatial resolution beyond the diffraction limit, increasing the palette of available materials, and reducing instrument cost.

Martin Wegener is a professor at Institute of Applied Physics of Karlsruhe Institute of Technology (KIT); since 2001 he has a joint appointment as department head at Institute of Nanotechnology (INT) of KIT, & acted as one of three directors at INT from 2016 to 2022. From 2001 to 2014 he was the coordinator of the DFG-Ctr. for Functional Nanostructures (CFN) at KIT. Since 2018 he is spokesperson of the Cluster of Excellence 3D Matter Made to Order. His research interests comprise ultrafast optics, (extreme) nonlinear optics, optical laser lithography, photonic crystals, optical, mechanical, electronic, and thermodynamic metamaterials, as well as transformation physics. This research has led to awards and honors, among which are the European Union René Descartes Prize 2005, Carl Zeiss Research Award (2006), SPIE Prism Award 2014, Nanoscribe GmbH, the Stifterverband Science Award – Erwin-Schrödinger Prize 2016, & the Technology Transfer Prize of the German Physical Society (DPG) 2018.
