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 ...
