High photon flux table-top coherent extreme ultraviolet source
Steffen Hädrich, Arno Klenke, Jan Rothhardt +6
High harmonic generation (HHG) enables extreme ultraviolet radiation with table-top setups. Its exceptional properties, such as coherence and (sub)-femtosecond pulse durations, hav…

Enhancing narrowband high order harmonic generation by Fano resonances
Jan Rothhardt, Steffen Hädrich, Stefan Demmler +4
Resonances in the photo-absorption spectrum of the generating medium can modify the spectrum of high order harmonics. In particular, window-type Fano resonances can reduce photo-ab…
