Abstract—This review contains theoretical study of resonant quantum electrodynamics processes in a pulsed
laser field. The approximation is examined when the pulse width is considerably greater than the characteristic
time of wave oscillations. The lepton’s interaction with the Coulomb potential of a nucleus and each other is
considered in the Born approximation. It is demonstrated that the resonant differential cross section of a process
in a pulsed light fields may considerably exceed the corresponding cross section in an absence of a laser field.
Results obtained may be experimentally verified by the scientific facilities at the SLAC National Accelerator
Laboratory and FAIR (Facility for Antiproton and Ion Research, Darmstadt, Germany) project.
