Title: Temporal coherence effects in multiple ionization of N{sub 2} via XUV pump-probe autocorrelation

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 N{sub 2} multiphoton-induced fragmentation into noncoincident N{sup 2+} and coincident N{sup 2+}+N{sup 2+} 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 {approx}12-fs substructure in the trace.
