Abstract

Using a split-mirror stage combined with a reaction microscope, nonlinear autocorrelation traces of XUV pulses from the Free-electron LASer at Hamburg were recorded for N₂ multiphoton-induced fragmentation into noncoincident N2⊃+ and coincident N2⊃++N2⊃+ channels. We find a pulse duration of 40±10 fs along with a sharp spike pointing to a coherence time of 4±1 fs, almost twice as short as in previous observations. Both are well reproduced by a simulation based on the partial-coherence model that includes the molecular dynamics leading to an ~12-fs substructure in the trace.
