The motions of electrons driven by the fields of relativistically intense laser pulses are analyzed for the linear polarization. The treatment is based on the numerical solution of the relativistic Newton's equation with the Lorentz force for laser beams with Gaussian transverse intensity distribution. The electromagnetic radiation of an electron interacting with a laser pulse is also studied. It is shown that: laser fields accelerate electrons both in the transverse and longitudinal directions and the electron radiation comprises short pulses having zeptosecond (and even subzeptosecond) durations (© 2009 WILEY‐VCH Verlag GmbH & Co.
