- Longitudinal coherence measurements of an extreme-ultraviolet free-electron laserW F Schlotter
Institute for Experimental Physics, University of Hamburg and Center for Free Electron Laser Science, 22761 Hamburg, Germany
Opt Lett 35:372-4. 2010..These data agree with the spectral bandwidth measurements made in the frequency domain. They exhibit two correlation time scales and the measured coherence curves have relevant implications for single-shot measurements...
- The extreme ultraviolet split and femtosecond delay unit at the plane grating monochromator beamline PG2 at FLASHF Sorgenfrei
Institut für Experimentalphysik and Centre for Free Electron Laser Science, Universitat Hamburg, Luruper Chaussee 149, 22761 Hamburg, Germany
Rev Sci Instrum 81:043107. 2010..To demonstrate the performance of this device, we have performed longitudinal coherence studies of FLASH radiation as well as measured the pulse length by nonlinear two-photon double-ionization in helium...
- Real-time observation of surface bond breaking with an x-ray laserM Dell'angela
University of Hamburg and Center for Free Electron Laser Science, Hamburg, Germany
Science 339:1302-5. 2013..Two distinct adsorption wells-chemisorbed and precursor state separated by an entropy barrier-explain the anomalously high prefactors often observed in desorption of molecules from metals...
