Nano-Optics and Ultrafast Dynamics
We investigate ultrafast electronic and structural dynamics in solids, nanostructures and surfaces. In particular, the group develops and applies new experimental techniques based on imaging and diffraction with ultrashort electron pulses. We operate unique instruments combining high spatial and temporal resolution, such as an Ultrafast Transmission Electron Microscope (UTEM) and Ultrafast Low-Energy Electron Diffraction (ULEED) setups.
In further activities, we study highly nonlinear optical processes in metallic nanostructures and their control by intense optical fields. Moreover, we have recently established laboratory-scale magnetic imaging using extreme-ultraviolet radiation from high-harmonic generation.
