   Sammanfattning : In this thesis we consider three QED phenomena in strong electromagnetic fields: Schwinger pair production, vacuum birefringence and radiation reaction. We study electron-positron pair production in a variety of field configurations and, using complex worldline instantons, reveal new insights into the case of fields with lightlike inhomogeneities.
