Velocity map imaging was implemented at the free electron laser in Hamburg to image atomic and molecular photoionization processes at a photon energy of 45.55 eV. High quality momentum distributions were recorded for a range of rare gases (He, Ne, Ar, Kr and Xe) and small molecules (H2, D2, O2, N2, CO2). This proof-of-principle experiment illustrates the potential for using velocity map imaging in order to study non-linear ionization and/or dissociation processes.
