Abstract

We report on calculations of the above threshold detachment ofF- by a few-cycle circularly polarized laser field, discussing the effects ofboth the carrier-envelope relative phase and the number of the cyclecontained in a pulse on the angular distribution of ejected photoelectron.The results are analyzed in terms of a two-step semiclassical model: afterthe electrons are detached through tunnelling their motion is determined bythe electric field pulse according to the classical dynamics laws.Anisotropies in the angular distributions of the electrons ejected on theplane perpendicular to the laser propagation direction are found that dependon the number of cycle of the laser pulse.
