Our calculations are based on the random-phase-approximation formalism, in terms of the dielectric function of the medium, where the effects of the laser field are included in the dynamical response. The main effects on the slowing down of the electrons are studied as a function of the intensity and frequency of the laser field, as well as a function of the projectile velocity. A modification of the electron inverse mean free path for plasmon and electron-hole excitations is obtained due to multiphoton-exchange processes.
