Abstract

Beat-wave acceleration of particles requires that the particle trajectories closely follow the constant-phase lines of the excited plasma wave.
Dephasing phenomena caused by plasma inhomogeneities and by relativistic frequency shifts and the accompanying self-phase modulation of the plasma wave are investigated. Parameter studies of beat-wave experiments indicate the plasma homogeneity will be a critical issue, especially with short wavelength lasers.
The plasmon wake suffers most strongly from dephasing effects which fact considerably reduces the efficiency of the wake region in beat-wave acceleration.
