  Electron-positron pair creation in collisions of a modulated laser pulse with
a high-energy photon (nonlinear Breit-Wheeler process) is studied by means of
strong-field quantum electrodynamics. It is shown that the driving pulse
modulations lead to appearance of comb structures in the energy spectra of
produced positrons (electrons). It is demonstrated that these combs result from
a coherent enhancement of probability amplitudes of pair creation from
different modulations of the laser pulse. Thus, resembling the Young-double
slit experiment for anti-matter (matter) waves.
