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…
