Redirection and Reshaping of Intense Extreme-Ultraviolet Radiation
Yu He, Alexander Magunia, Harijyoti Mandal +29
The goal to control short-wavelength radiation for the investigation and manipulation of ultrafast dynamics in quantum systems coevolves with the growing availability of extreme-ul…
Coherent all X-ray four wave mixing at core shell resonances
Ana Sofia Morillo-Candas, Sven Martin Augustin, Eduard Prat +17
Nonlinear wave mixing in the X-ray range can provide valuable insights into the structural and electron dynamics of atomic and molecular systems on ultrafast time scales, with stat…
Transmission spectroscopy of CF molecules in intense x-ray fields
Rui Jin, Adam Fouda, Alexander Magunia +19
The nonlinear interaction of x-rays with matter is at the heart of understanding and controlling ultrafast molecular dynamics from an atom-specific viewpoint, providing new scienti…
Resolving Vibrations in a Polyatomic Molecule with Femtometer Precision
Patrick Rupprecht, Lennart Aufleger, Simon Heinze +9
We measure molecular vibrations with femtometer precision using time-resolved x-ray absorption spectroscopy. For a demonstration, a Raman process excites the A mode in gas-p…
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…
Strong-field extreme-ultraviolet dressing of atomic double excitation
Christian Ott, Lennart Aufleger, Thomas Ding +21
We report on the experimental observation of strong-field dressing of an autoionizing two-electron state in helium with intense extreme-ultraviolet laser pulses from a free-electro…
In situ characterization of few-cycle laser pulses in transient absorption spectroscopy
Alexander Blättermann, Christian Ott, Andreas Kaldun +5
Attosecond transient absorption spectroscopy has thus far been lacking the capability to simultaneously characterize the intense laser pulses at work within a time-resolved quantum…
Time-resolved four-wave-mixing spectroscopy for inner-valence transitions
Thomas Ding, Christian Ott, Andreas Kaldun +9
Non-collinear four-wave mixing (FWM) techniques at near-infrared (NIR), visible, and ultraviolet frequencies have been widely used to map vibrational and electronic couplings, typi…
