Nondipole strong-field approximation for above-threshold ionization in a few-cycle pulse

The ionization of atoms and molecules by strong laser fields has been studied extensively, both theoretically experimentally. strong-field approximation (SFA) allows for the analytical solution Schr\"odinger equation accurately predicts behavior processes in intense fields. Over past decade, there a growing interest study nondipole effects these processes. However, such predictions have so far limited to monochromatic driving fields, while experiments often employ quite short pulses. In this paper, we therefore present an extension SFA that also incorporating more complicated temporal structure few-cycle pulse. By extension, prediction so-called peak shifts is significantly improved, ability control pulse inducing above-threshold greatly enhanced. enhanced over characteristics results accurate shifts. Our show better agreement with experimental investigations compared previous theoretical studies.
