High temporal and spectral resolution of stimulated x-ray Raman signals with stochastic free-electron-laser pulses
Stefano M. Cavaletto, Daniel Keefer, Shaul Mukamel
The chaotic nature of x-ray free-electron-laser pulses is a major bottleneck that has limited the joint temporal and spectral resolution of spectroscopic measurements. We show how…
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…
