Ultrafast extreme ultraviolet (EUV; 5-100 nm) and X-ray (0.01-5 nm) sources enable scientists to see and control the internal structure of terials at the nanometer scale, and study the dynamics of electrons and molecules at the femtosecond-to-attosecond resolution. While a few large ($1 billion scale) accelerator-based synchrotron and freeelectron laser radiation facilities are able to generate ultrafast, bright EUV/X-ray pulses,
table-top sources are highly desired; they become crucial to create entirely new applications and make those powerful techniques - that have been demonstrated on large synchrotron radiation sources - accessible to a much larger, University-based community. The proposed Helmholtz Young Investigator Group sets to develop the key optical technologies needed to enable table-top ultrafast bright EUV/X-ray sources: (i) high-power Yb-fiber laser frequency combs, (ii) optical enhancement cavity, and (iii) mid-IR and terahertz ultrafast sources for pump-probe experiments.
