The most exciting phrase to hear in science, the one that heralds new discoveries, is not "Eureka!" but "That's funny..." Isaac Asimov
We are developing of what might be termed the next generation synchrotron lightsource, based on a novel laser-driven electron acceleration scheme. Compared to a conventional source, this scheme allows a more than thousandfold reduction in spatial dimensions to a table-top X-ray source, which is capable of generating intrinsically ultrashort pulses.>> more
Only a few experimental studies exist in the fields of nonlinear X-ray optics and nonlinear quantum electrodynamics (QED) to date. We use novel high-intensity optical and X-ray lasers to investigate these widely unexplored territories of physics.
Ultrashort, relativistic electron beams are able to generate ultrashort pulses at TeraHertz (THz) wavelengths with unprecedented intensities. We use such pulses to investigate strong-field THz-matter interaction and its ultrafast dynamics.
