We present a two color investigation of the hydrogen molecule to benchmark our tabletop experiment dedicated to ultrafast investigations of electronic correlations in atoms and molecules from the near infrared (NIR) to the extreme ultraviolet (EUV) range. Our setup focuses on the study of dissociating molecules by different pump-probe techniques aiming to obtain invaluable and novel insights into atomic and molecular dynamics. For this purpose, we have built a femtosecond laser driven EUV source based on high harmonic generation (HHG) combining it with a pulsed molecular jet, a delay-line based velocity map imaging (VMI) detector and a time-of-flight (TOF) spectrometer. We are going to show first experimental as well as theoretical results quantifying the performance of our apparatus having captured and analysed the angular ion momentum distribution of the photo-induced dissociation process of hydrogen, irradiated by ultrafast 800 nm and 400 nm laser fields.
