One-Color and Two-Color Two-Step Absorption for 3D Laser Printing

14 April 2022 12:00 - 13:00
Eastern Daylight/Summer Time (US & Canada) (UTC -04:00)Two-photon or multi-photon absorption based 3D laser nanoprinting has become an established, versatile and commercially available technology for the making of complex three-dimensional nano-and micro-architectures with applications in optics, mechanics, and biology. In this webinar hosted by the NonImaging Optical Design Technical Group, Martin Wegener will discuss replacing two-photon absorption by two sequential one-photon absorption processes (nicknamed "two-step absorption"). This replacement allows for using inexpensive and compact continuous-wave lasers rather than femtosecond lasers. This includes one-color two-step absorption for scanning-focus 3D nanoprinting and two-color two-step absorption for parallelized light-sheet 3D microprinting.

About The Presenter: Martin Wegener, Karlsruhe Institute of Technology
After completing his diploma and PhD in physics at Johann Wolfgang Goethe-Universität Frankfurt (Germany) in 1986 and 1987, respectively, he spent two years as a postdoc at AT&T Bell Laboratories in Holmdel (U.S.A.). From 1990-1995 he was professor (C3) at Universität Dortmund (Germany), since 1995 he is professor (C4, later W3) 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, since 2016 he is one of the three directors at INT. From 2001-2014 he was the coordinator of the DFG-Center 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.
