Mott scattering in a field of two pulsed laser waves

Abstract

Laser-modified Mott scattering in a field of two unidirectional pulsed waves is considered. The primary object of research is the cross section distribution of the final electron energy at a fixed geometry of the scattering process. The parametric interference effect is manifested within the plane formed by both the direction of the laser-wave propagation and the initial electron momentum (the interference region). The induced processes of the correlated emission and absorption of external-field photons are preferred in the interference region for the circular polarization of both laser waves. A comparative analysis of the electron energy spectra is provided in the interference region and the region where the parametric interference effect is hardly manifested, at the same parameters of a laser field and the initial electron energy. The cross section of laser-modified electron-nucleus scattering at the specified final electron energy in the interference region may be one order of magnitude greater than the cross section at the other geometry of scattering.

Supercontinuum in ionization by relativistically intense and short laser pulses: Ionization without interference and its time analysis

“…In particular, such diverse phenomena have been studied as the vacuum polarization induced Young interference [25], the Kapitza-Dirac effect [26,27], interference effects in Compton and Thomson scattering (see, e.g., [28,29]), and in lasermodified Mott scattering [30,31], the coherent comb structures created by a finite train of short pulses in the Compton [32,33], Breit-Wheeler [34], and ionization [35] processes, which can be used for the diagnostics of relativistically intense laser pulses [36,37].…”

“…Recently, with the development of lasers generating relativistically intense and very short pulses, similar interference patterns have been investigated in the relativistic strong-field quantum electrodynamics [21][22][23]. In particular, such diverse phenomena have been studied as the vacuum polarization induced Young interference [24], the Kapitza-Dirac effect [25,26], interference effects in Compton and Thomson scattering (see, e.g., [27,28]), and in laser-modified Mott scattering [29,30], the coherent comb structures created by a finite train of short pulses in the Compton [31,32] and Breit-Wheeler [33] processes, which can be used for the diagnostics of relativistically intense laser pulses [34].…”

Electron Scattering Processes in Non-Monochromatic and Relativistically Intense Laser Fields

“…The same author also studied the case of free-free transitions of a fermion in the light pulse [131]. In recent years, Lebed' [132,133] and Lebed' and Roshchupkin [134] centered their attention on the Mott scattering assisted by pulses of electromagnetic radiation (see also the reviews [101,102]). In particular, the use of circularly-polarized bichromatic laser fields and the interference effects associated to them are described in Refs.…”

Relativistic elastic scattering of an electron by a muon in the field of a circularly polarized electromagnetic wave

“…Roshchupkin et al developed the theory of the electron scattering on a nucleus in the field of two plane electromagnetic waves [10][11][12][13]. Lebed' et al studied Mott scattering process in the presence of one [14] or two [15] laser pulses. Then, with increasing laser intensities, other scattering processes were investigated.…”
