Interrogating the temporal coherence of EUV frequency combs with highly charged ions
Chunhai Lyu, Stefano M. Cavaletto, Christoph H. Keitel +1
A scheme to infer the temporal coherence of EUV frequency combs generated from intra-cavity high-order harmonic generation is put forward. The excitation dynamics of highly charged…
Nonlinear coherence effects in transient-absorption ion spectroscopy with stochastic extreme-ultraviolet free-electron laser pulses
Thomas Ding, Marc Rebholz, Lennart Aufleger +21
We demonstrate time-resolved nonlinear extreme-ultraviolet absorption spectroscopy on multiply charged ions, here applied to the doubly charged neon ion, driven by a phase-locked s…
Light-induced states in the transient-absorption spectrum of a periodically pumped strong-field-excited system
Juliane Haug, Stefano M. Cavaletto
The transient-absorption spectrum of a -type three-level system is investigated, when this is periodically excited by a train of equally spaced, -like pump pulses as, e.g., f…
Narrow-band hard-x-ray lasing
Chunhai Lyu, Stefano M. Cavaletto, Christoph H. Keitel +1
Since the advent of x-ray free-electron lasers (XFELs), considerable efforts have been devoted to achieve x-ray pulses with better temporal coherence. Here, we put forward a scheme…
Real-time reconstruction of complex non-equilibrium quantum dynamics of matter
Veit Stooß, Stefano M. Cavaletto, Alexander Blättermann +4
Causality implies that by measuring an absorption spectrum, the time-dependent linear response function can be retrieved. Recent experiments suggest a link between the shape of spe…
Phase reconstruction of strong-field excited systems by transient-absorption spectroscopy
Z. Liu, S. M. Cavaletto, C. Ott +5
We study the evolution of a V-type three-level system, whose two resonances are coherently excited and coupled by two ultrashort laser pump and probe pulses, separated by a varying…
