Collective enhancement of above threshold ionization by resonantly excited helium nanodroplets
R. Michiels, M. Abu-samha, L. B. Madsen +18
Clusters and nanodroplets hold the promise of enhancing high-order nonlinear optical effects due to their high local density. However, only moderate enhancement has been demonstrat…
Unravelling the Full Relaxation Dynamics of Superexcited Helium Nanodroplets
Jakob D. Asmussen, Rupert Michiels, Katrin Dulitz +20
The relaxation dynamics of superexcited superfluid He nanodroplets is thoroughly investigated by means of extreme-ultraviolet (XUV) femtosecond electron and ion spectroscopy comple…
High-Gain Harmonic Generation with temporally overlapping seed pulses and application to ultrafast spectroscopy
Andreas Wituschek, Lukas Bruder, Enrico Allaria +22
Collinear double-pulse seeding of the High-Gain Harmonic Generation (HGHG) process in a free-electron laser (FEL) is a promising approach to facilitate various coherent nonlinear s…
Phase cycling of extreme ultraviolet pulse sequences generated in rare gases
Andreas Wituschek, Oleg Kornilov, Tobias Witting +4
The development of schemes for coherent nonlinear time-domain spectroscopy in the extreme-ultraviolet regime (XUV) has so far been impeded by experimental difficulties that arise a…
Tracking Attosecond Electronic Coherences Using Phase-Manipulated Extreme Ultraviolet Pulses
Andreas Wituschek, Lukas Bruder, Enrico Allaria +31
The recent development of ultrafast extreme ultraviolet (XUV) coherent light sources bears great potential for a better understanding of the structure and dynamics of matter. Promi…
A simple photoionization scheme for characterizing electron and ion spectrometers
A. Wituschek, J. von Vangerow, J. Grzesiak +2
We present a simple diode laser-based photoionization scheme for generating electrons and ions with well-defined spatial and energetic (<2 eV) structures. This scheme can easily be…
