Towards an UA Ruhr Ultrafast Laser Science Center: Tailored fs-XUV Beamline for Photoemission Spectroscopy

Ultrafast lasers (UL) have been at the forefront of many scientific breakthroughs since their invention in the 90s and have progressed from specialized lab tools to commercial equipment extensively used in both science and industry. In this progress line, those who were at the forefront of technology could access unique regimes of light-matter interaction, make breakthrough discoveries and push science forward. Nevertheless, UL science and technology often remain disconnected from each other– laser developers seeking high-impact applications for their unique systems, and experimentalists settling with available commercial performance and struggling with the lack of flexibility of the available parameters.
In this two-year bi-lateral project, our target is to build an ultrafast spectroscopic tool with unique performance and flexibility based on state-of-the-art ultrafast laser technology specifically tailored for photoemission spectroscopy of targeted systems. We will build a kilowatt-class average power modelocked thin-disk oscillator operating at MHz repetition rate, which will drive a single-pass XUV beamline with state-of-the-art photon energy, flux and linewidth and will demonstrate the potential of this tailored system for time-resolved photoelectron spectroscopy.The high-impact outcomes of this work will form a solid base to apply to an ERC synergy grant on the optical control of two-dimensional electronic systems. At the same time, this project will act as a catalyzing example of the value of combining UL science and technology, thus setting a first stepstone towards a long-term vision of a larger collaborative effort in the UA Ruhr – the
UA Ruhr Ultrafast Laser Science Center – that will bridge UL science, ultrafast spectroscopy and technology.
