Spatial and temporal coherence properties of single free-electron laser pulses
A. Singer, F. Sorgenfrei, A. P. Mancuso +16
The experimental characterization of the spatial and temporal coherence properties of the free-electron laser in Hamburg (FLASH) at a wavelength of 8.0 nm is presented. Double pinh…
Dynamics of colloidal crystals studied by pump-probe experiments at FLASH
R. Dronyak, J. Gulden, O. M. Yefanov +20
We present a time-resolved infrared (IR) pump and extreme-ultraviolet (XUV) probe diffraction experiment to investigate ultrafast structural dynamics in colloidal crystals with pic…
Watching the acetylene vinylidene intramolecular reaction in real time
Y. H. Jiang, A. Senftleben, A. Rudenko +18
It is a long-standing dream of scientists to capture the ultra-fast dynamics of molecular or chemical reactions in real time and to make a molecular movie. With free-electron laser…
Hanbury Brown and Twiss interferometry at a free-electron laser
A. Singer, U. Lorenz, F. Sorgenfrei +11
We present measurements of second- and higher-order intensity correlation functions (so-called Hanbury Brown and Twiss experiment) performed at the free-electron laser (FEL) FLASH…
Double diffraction imaging of X-ray induced structural dynamics in single free nanoparticles
M. Sauppe, T. Bischoff, C. Bomme +22
Because of their high photon flux, X-ray free-electron lasers (FEL) allow to resolve the structure of individual nanoparticles via coherent diffractive imaging (CDI) within a singl…
Time-Resolved Measurement of Interatomic Coulombic Decay in Ne_2
K. Schnorr, A. Senftleben, M. Kurka +24
The lifetime of interatomic Coulombic decay (ICD) [L. S. Cederbaum et al., Phys. Rev. Lett. 79, 4778 (1997)] in Ne_2 is determined via an extreme ultraviolet pump-probe experiment…
In-situ observation of the formation of laser-induced periodic surface structures with extreme spatial and temporal resolution
K. Sokolowski-Tinten, J. Bonse, A. Barty +12
Irradiation of solid surfaces with intense ultrashort laser pulses represents a unique way of depositing energy into materials. It allows to realize states of extreme electronic ex…
