 Title INTERACTION OF ATOMIC-HYDROGEN WITH AN ULTRA-SHORT LASER-PULSE HAVING A PEDESTAL Publication Type Journal Article Year of Publication 1991 Veniard, V, Piraux, B Journal OPTICS COMMUNICATIONS Volume 84 Issue 5-6 Pagination 264-268 Date Published AUG 1 ISSN 0030-4018 Keywords paper Abstract We study the electron energy spectrum resulting from the interaction of atomic hydrogen initially in the 2s state with an ultra-short laser pulse having a pedestal{''}, of the sort produced by chirped pulse amplification. As a first step, we treat this problem within second-order time-dependent perturbation theory. The effect of the pedestal is discussed in detail. Full Text
