Claus Ropers

from Wikipedia, the free encyclopedia

Claus Ropers , (* 1977 in Stade ) is a German solid-state physicist who deals with nano-optics and ultrafast dynamics.

Ropers studied at the University of Göttingen and Berkeley and received his doctorate from the Humboldt University in Berlin in 2007 (Femtosecond excitations in metallic nanostructures: from ultrafast light confinement to a local electron source). He received the Carl Ramsauer Prize for the dissertation prepared at the Max Born Institute for Nonlinear Optics and Short-Term Spectroscopy. Since 2008 he has been group leader and professor at the IV. Physics Institute of the University of Göttingen (Courant Research Center).

He investigates the ultrafast dynamics of solids and nanostructures with innovative instruments based on ultrashort laser-induced electron pulses, for example in ultrafast transmission electron microscopy (UTEM) and low-energy electron diffraction (ULEED). In addition, he investigates nonlinear optical processes in metal nanostructures: Localized photoemission from metallic nano tips (strong field photodynamics) and their terahertz control, generation of extreme UV in plasmonic metallic nano structures, lensless imaging with high harmonics.

In 2007 he reported with D. Solli about “ monster waves ” (rogue waves) in optics.

In 2008 he received the Nanoscience Prize of the Working Group of Nanotechnology Competence Centers in Germany and the Carl Ramsauer Prize of the Berlin and Potsdam Universities, in 2010 the Robert Wichard Pohl Medal of the Georg August University in Göttingen and in 2013 the Walter Schottky -Prize of the German Physical Society . In 2017 he received the Klung Wilhelmy Science Prize and in 2018 the Gottfried Wilhelm Leibniz Prize . For 2019 Ropers was awarded the Ernst Ruska Prize .
