β¦ Synopsis
The excitation of an N-level quantum oscillator by a strong oscillating electrtc fieId in the presence of external perturbations can in general be described by a Boltzmann equation for the density matrix. In this paper it is shown that under certain circumstances this may be reduced to a set of rate equations for the level populations. In contrast to the weak field situation, these rate equations explicitly contain mutti-photon transition rates.

Modern lasers are yet unable to cause electron-positron pair production in vacuum, however it is possible to notice considerable influence of vacuum polarization on radiation that propagates in such medium. The field strength of modern lasers is not strong enough for creation of electron-positron pa
