In dielectric laser acceleration, nanostructures etched into silicon are used to convert free-space ultrashort laser pulses to accelerate particles. This current approach, namely, illuminating the structure with a laser directed nearly horizontally to the substrate, is experimentally challenging and...

A defense under very special circumstances, via Zoom -- everything went well, in terms of content anyway, and technically there were only two minimal hiccups. Constanze Gerner defended her dissertation with great success in a very lively defense despite the purely virtual meeting. The Zoom reception...

Our early student Tamara Pröbster was awarded 1st prize in the field of physics in the Bavarian state competition Jugend forscht. In her research project at our chair, Tamara investigated how ultrafast light-induced electron emission from graphene can be decoupled into different processes - accordin...

When two-color femtosecond laser pulses interact with matter, electrons can be emitted through various excitation pathways involving different combinations of photons from the individual colors. Quantum interference between these pathways gives rise to a strong oscillation of the photoemitted electr...

In our most recent publication in Applied Physics Letters we demonstrate the splitting of an electron beam in the energy range from 200 to 1700eV using auto-ponderomotive electron optics (see also preceding news flash here). The ponderomotive potential is shaped in such a way that the minimum at th...

The control of electron and ion beams are of great importance for many areas of research and technology. Both are used, for example, in electron microscopes but also in medical patient treatment. In our latest publication in Nature Communications, we report on the development of auto- ponderomotive ...

Strict anti-virus propagation measures have again forced an apparently rather boring defense, but in terms of content this has not detracted from the matter: Norbert Schönenberger has defended his dissertation with great success. Congratulations!

Our long-time partner and frequent and especially welcome guest in Erlangen Mark Stockman PhD DSc, Regents Professor of Physics and Director of the Center for Nano Optics at Georgia State University, died on November 11th at the age of 73 years. Professor Stockman left his mark on entire fields of p...

Under the current corona protection conditions it is again hardly imaginable, but in September it was possible: We spent two and a half wonderful and highly interesting days at Hirschberg Castle in the pretty Altmühltal valley, to bring each other up to date and to be able to discuss our science in ...
