Some features of the momentum distribution of the residual e − e + pair plasma (EPPP)
createdfromthevacuuminastronglaserfieldinthemultiphotondomainγ = 2πE c λ c /E 0 λ >
1 (E 0 and λ are the field strength amplitude and wavelength of the external electric field)
areinvestigated in the low density approximation to the nonperturbative kinetic approach
(e.g., [1, 2]). The traditional multiphoton mechanism of EPPP excitations is examined in
comparison with the new photon cluster mechanism found in [3], where a photon cluster
is introduced as a system of identical photons that act as one photon having the total
energy of this system. We analyze the role of the simplest elementary photon processes
in the EPPP with and without the assistance of the photon clusters, as well as the case
of large photon numbers. These calculations are intended to find simple estimations of
the secondary processes associated with the dynamical Schwinger effect [4, 5, 6, 7].
