Yi. Salamin et Fhm. Faisal, Ultrahigh electron acceleration and Compton emission spectra in a superintense laser pulse and a uniform axial magnetic field - art. no. 043801, PHYS REV A, 6104(4), 2000, pp. 3801
Exact expressions for the electron trajectory and energy are discussed, whi
ch predict very high acceleration, in vacuum, by a laser field and a unifor
m magnetic field. The laser field is modeled by a sin(2) pulse and the init
ial electron motion, propagation of the laser pulse, and the magnetic field
are all chosen in the same direction. An acceleration gradient in the TeV/
m range within a very short travel distance of the electron is shown to be
possible when a resonance condition is initially met. The acceleration and
radiation properties are investigated using a recent analytic solution [F.
H. M. Faisal and Y. I. Salamin, Phys. Rev. A 60, 2505 (1999)] of the corres
ponding relativistic equations of motion in the laboratory frame. The radia
tion losses are shown to remain small under the resonance condition and the
associated weak emission spectra are found to be characterized by highly i
rregular line distributions.
