  We study the creation of electron-positron pairs in the superposition of a
nuclear Coulomb field and a two-color laser field of high intensity. Our focus
lies on quantum interference effects, which may arise if the two laser
frequencies are commensurable. We show that the interference manifests in the
angular distributions of the created particles, which are discussed in the
nuclear rest frame and the laboratory frame. Additionally, we demonstrate that
the total pair-production rates can be affected by interference and identify
the relative phase between the two laser modes, which optimizes the
pair-production yield.
