- 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
, , 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...
