Until recently the investigation of the interaction of strong light fields with matter at short wavelengths beyond the ultraviolet spectral range was hindered by the lack of sufficiently intense light sources. The production of gigawatt radiation in the vacuum ultraviolet range with intensities up to 1013 W/cm2 at the DESY free-electron laser opened the door to such studies. First experiments with clusters have shown that in principle a highly ionised medium is formed, which absorbs unexpectedly strong and finally disintegrates by Coulomb explosion. This contribution will first review the results from the FEL experiment and then turn towards forthcoming experiments. Besides future work at the VUV-FEL, complementary time resolved cluster studies using high harmonic generation (HHG)as intense VUV light source will be presented.
