“…This effect has been also proposed for the coherent X-ray generation due to the quantum reflection of an electron beam from a laser-field phase lattice [200] and for the monochromatization of charged-particle beams by a laser pulse [201]. It has recently been shown that this mechanism may be relevant for atom acceleration as well [202].…”

“…Finally, we note that, adopting the same scaling of Eqs. (15)- (17) in Eq. (5), this can be interpreted as a Schrödinger equation for a single particle with a "mass"ρ 3/2 in a selfconsistent pendulum potential.…”

Free Electron Laser (FEL) and Collective Atomic Recoil Laser (CARL) are described by the same model of classical equations for properly defined scaled variables. These equations are extended to the quantum domain describing the particle's motion by a Schrödinger equation coupled to a selfconsistent radiation field. The model depends on a single collective parameterρ which represents the maximum number of photons emitted per particle. We demonstrate that the classical model is recovered in the limitρ ≫ 1, in which the Wigner function associated to the Schrödinger equation obeys to the classical Vlasov equation. On the contrary, forρ ≤ 1, a new quantum regime is obtained in which both FELs and CARLs behave as a two-state system coupled to the self-consistent radiation field and described by Maxwell-Bloch equations.

“…This estimate is in agreement with Refs. [35,36]. The dense plasma exists for the duration of a laser pulse but vanishes almost completely after switching off the field.…”

We consider the possibility of experimental verification of vacuum e + e − pair creation at the focus of two counter-propagating optical laser beams with intensities 10 20 -10 22 W/cm 2 , achievable with presentday petawatt lasers, and approaching the Schwinger limit: 10 29 W/cm 2 to be reached at ELI. Our approach is based on the collisionless kinetic equation for the evolution of the e + and e − distribution functions governed by a non-Markovian source term for pair production. As possible experimental signals of vacuum pair production we consider e + e − annihilation into γ-pairs and the refraction of a high-frequency probe laser beam by the produced e + e − plasma. We discuss the dependence of the dynamical pair production process on laser wavelength, with special emphasis on applications in the X-ray domain (X-FEL), as well as the prospects for µ + µ − and π + π − pair creation at high-intensity lasers. We investigate perspectives for using high-intensity lasers as "boosters" of ion beams in the few-GeV per nucleon range, which is relevant, e.g., to the exploration of the QCD phase transition in laboratory experiments.
