Improved stabilization scheme for extreme ultraviolet quantum interference experiments
Daniel Uhl, Andreas Wituschek, Ulrich Bangert +18
Interferometric pump-probe experiments in the extreme ultraviolet (XUV) domain are experimentally very challenging due to the high phase stability required between the XUV pulses.…
High-resolution two-dimensional electronic spectroscopy reveals homogeneous line profiles in isolated nanoparticles
Ulrich Bangert, Frank Stienkemeier, Lukas Bruder
Doped clusters in the gas phase provide nanoconfined model systems for the study of system-bath interactions. To gain insight into interaction mechanisms between chromophores and t…
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…
A flexible and scalable, fully software-based lock-in amplifier for nonlinear spectroscopy
Daniel Uhl, Lukas Bruder, Frank Stienkemeier
We demonstrate a cost-effective, fully software-based lock-in amplifier (LIA) implemented on a commercial computer. The device is designed for application in nonlinear spectroscopy…
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…
