Abstract
In this experiment we used an 800Â nm laser to generate high-order harmonics in a gas cell filled with Argon. Of those photons, a harmonic with 42Â eV was selected by using a time-preserving grating monochromator. Employing a modified Mach-Zehnder type Fourier transform spectrometer for the VUV/XUV it was possible to measure the temporal coherence of the selected photons to about 6Â fs. We demonstrated that not only could this kind of measurement be performed with a Fourier transform spectrometer, but also with some spatial resolution without modifying the XUV source or the spectrometer.
