Time-resolved quantum beats in the fluorescence of helium resonantly excited by XUV radiation
AC LaForge, A Benediktovitch, V Sukharnikov +18
We report on the observation of time-resolved quantum beats in the helium fluorescence from the transition 1s3p -> 1s2s, where the initial state is excited by XUV free-electron las…
Characterization of soft X-ray echo-enabled harmonic generation free-electron laser pulses in the presence of incoherent energy modulations
N. S. Mirian, G. Perosa, E. Hemsing +14
Echo-enabled harmonic generation free-electron lasers (EEHG FELs) are promising candidates to produce fully coherent soft x-ray pulses by virtue of efficient high harmonic frequenc…
Ultrafast adsorbate excitation probed with sub-ps resolution XAS
Elias Diesen, Hsin-Yi Wang, Simon Schreck +24
We use a pump-probe scheme to measure the time evolution of the C K-edge X-ray absorption spectrum (XAS) from CO/Ru(0001) after excitation by an ultrashort high-intensity optical l…
Non-linear self-driven spectral tuning of Extreme Ultraviolet Femtosecond Pulses in monoatomic materials
Carino Ferrante, Emiliano Principi, Andrea Marini +9
Self-action nonlinearity is a key aspect -- either as a foundational element or a detrimental factor -- of several optical spectroscopies and photonic devices. Supercontinuum gener…
Observation of magnetic helicoidal dichroism with extreme ultraviolet light vortices
Mauro Fanciulli, Matteo Pancaldi, Emanuele Pedersoli +17
We report on the experimental evidence of magnetic helicoidal dichroism, observed in the interaction of an extreme ultraviolet vortex beam carrying orbital angular momentum with a…
