The combination of ultracold atomic systems and ultrafast laser pulses promises insight into the coherence properties of macroscopic dissipative quantum systems and enables the preparation of hybrid quantum systems through local ionization of atoms in strong laser fields. Here, we report on our progress in setting up a quantum gas machine where the ultracold gases are optically transported into the focal region of the femtosecond laser beam. Our setup aims for counting ions while detecting the impact pattern of the photoelectrons. Furthermore, we report on quantitative studies of strong-field ionization of a Bose-Einstein condensate via loss measurements and pulsed momentum transfer due to dipole forces.
