Water window soft x-ray source enabled by 25-W few-cycle mid-IR OPCPA at 100 kHz

Justinas Pupeikis, Pierre-Alexis Chevreuil, Nicolas Bigler +3

Coherent soft x-ray (SXR) sources enable fundamental studies in the important water window spectral region. Until now, such sources have been limited to repetition rates of 1 kHz o…

Time delays from one-photon transitions in the continuum

Jaco Fuchs, Nicolas Douguet, Stefan Donsa +5

Attosecond photoionisation time delays reveal information about the potential energy landscape an outgoing electron wavepacket probes upon ionisation. In this study we experimental…

Sub-cycle time resolution of multi-photon momentum transfer in strong-field ionization

Benjamin Willenberg, Jochen Maurer, Benedikt W. Mayer +1

During multi-photon ionization of an atom it is well understood how the involved photons transfer their energy to the ion and the photoelectron. However, the transfer of the photon…
