In the present paper we apply path integral methods on the study of the interaction of circularly polarized pulsed coherent photonic states with one active electron atoms. We integrate over the photonic field, perform the angular decomposition over the derived electron’s path integral and study the relevant sign solved propagator. We apply our methods on the ionization of the hydrogen atom and give results in the case of one or two consecutive pulses.
