We demonstrate that currents induced in graphene by ultrashort laser
pulses are sensitive to the exact shape of the electric-field waveform.
By increasing the field strength, we found a transition of the
light–matter interaction from the weak-field to the strong-field regime
at around 2 V/nm, where intraband dynamics influence interband
transitions. In this strong-field regime, the light-matter interaction
can be described by the wavenumber trajectories of electrons in the
reciprocal space. For linearly polarized light the electron dynamics are
governed by repeated sub-optical-cycle Landau-Zener transitions between
the valence- and conduction band, resulting in Landau-Zener-Stuckelberg
interference, whereas for circular polarized light this interference is
