Attosecond Physics builds on the properties of electron wave packets created by strong-field ionization close to the maxima of the field oscillations which are subsequently driven by the strong laser field on a sub-cycle time scale [1]. These wave packets can lead to interference structures in energy or momentum space. While interference of wave packets created during different field cycles (inter-cycle) give rise to the well-known above-threshold ionization (ATI) peaks, interference of wave packets that are created during the same laser cycle (intra-cycle) can lead to a hologram of the binding potential [2,3].
