INFLUENCE OF THE SPATIAL AND TEMPORAL DISTRIBUTION OF AN INCIDENT LASER BEAM PROFILE ON THE ENERGY DISTRIBUTION OF IONIZED PHOTOELECTRONS

We discuss the effects of two different spatial and temporal laser beam profiles on the energy distribution of ionized photoelectrons. Two types of profiles of laser radiation, Gaussian and Lorentzian, are considered. The influence of the nonzero initial momentum of ejected photoelectrons is observed. We find that selection of the laser beam profile influences the maximal energy distribution. It is also shown that the nonzero initial electron momentum has a more significant influence for the Lorentzian beam profile.
