Abstract:

Inner shell atomic electrons that are tunnel ionized in multi-petawatt class laser pulses are accelerated, in vacuum, to multi-GeV energies in the forward direction. In extreme fields, tunnel ionized electrons can be brought to the speed of light so abruptly, that they stay in the same phase of the laser field throughout significant portions of the confocal region. An analysis of the acceleration process is given, and relativistically covariant four-dimensional numerical calculations especially suited for extreme fields are carried out. Radiation reaction is included, and the latest relativistic tunneling ionization theories are used to spawn the simulated electrons. An experimental configuration is suggested, utilizing the 10 petawatt ELI-NP laser, and plasma lens assisted focusing.
