The motions of electrons driven by the fields of relativistically intense laser pulses for both linear and
circular polarizations are analyzed. The treatment is based on the numerical solution of Newton’s equation with
the Lorentz force. The electromagnetic radiation of an electron interacting with a laser pulse is studied. It is
shown that this radiation comprises short pulses having zeptosecond (subattosecond) durations.
