Relativistic nanophotonics

The project is supported by the Swedish Research Council (VR) by a Research Environment Grant

Our ambitious objective is to push the frontiers of the shortest electron bunches by combining cutting-edge instrumentation and leading expertise in laser, plasma and optical physics. We will develop a fundamentally new source of electron bunches with properties tailored by our unique high intensity laser system, delivering quasi-single optical-cycle pulses that irradiate nanometer-sized targets. These targets will be positioned in vacuum without mechanical support using an optical trap and active stabilization. In order to understand the target suspension and the electron dynamics, state-of-the-art simulations will be performed.

Groundbreaking results are expected, among others entering the attosecond regime with relativistic electrons. This will open the way for novel time-resolved photography of electron dynamics, and for attosecond x-ray generation, with application in light-driven electronics, bio-medical structure determination, and next-level temporal metrology.
