Abstract
A method for generating an ultrashort electron beam from a resonantly excited nonlinear wake field is proposed using a short laser pulse with a relativistic intensity. The considerable amount of electrons up to 10 are extracted from an appropriate thin plasma layer. When the laser intensity is highly relativistic, the electron beam is singly bunched and has a pulse length less than the laser wavelength and a large energy spread with a maximum energy of tens of MeV.
