Abstract
We study finite-size effects in the process of e+ e− pair production via the non-linear Breit-Wheeler process in ultra short laser pulses. Based on the Nikishov-Ritus method we use laser dressed electron and positron wave functions to derive the differential and total pair production cross section, focusing on the effects of a finite pulse duration. Hence, we go beyond the infinite laser pulse approximation and provide a more exact description of experiments with modern femtosecond laser systems.
