Röntgen Prize to Roy Shiloh
This year’s Röntgen Prize of the University of Giessen went to our former postdoc and current professor at the Hebrew University in Jerusalem, Dr. Roy Shiloh. He received the 15,000 euro prize for his outstanding contributions to the realization of a photonic particle accelerator. As it was mentioned in the award ceremony, Wilhelm Röntgen needed […]

Retreat in the Bavarian Forest
This year we again retreated for two and a half days to be able to discuss our projects intensively on the basis of presentations – and to listen to four more excellent presentations by invited guests. This year’s guests were Dr. Thilo Egenolf from Darmstadt, Prof. Christoph Lemell from Vienna, Prof. Martin Kozák from Prague […]

Coherent electron acceleration using photonic nanostructures – published in Nature
Optical near-fields excited by ultra-short laser pulses in a silicon-based nanophotonic structure can accelerate free electrons. This is known as dielectric laser acceleration (DLA). This new method allows much higher acceleration gradients to be achieved in a smaller space compared to conventional accelerators based on radio frequency waves. It exploits the high damage threshold of […]

Method for simultaneous measurement of the work function and the field reduction factor – published in Review of Scientific Instruments.
A main research focus at our chair is the investigation of light-matter interaction on metals on ultrafast time scales. For this purpose, we focus ultrashort laser pulses on metallic needle tips and investigate the emitted electrons. Important parameters of these tips are the work function, as well as the static electric field at the end […]
