Abstract

The motion of an electron in the fields of relativistic-intensity linearly and circularly polarised laser radiation is analysed. The analysis is based on the numerical solution of the Newton equation with the Lorentz force. The electromagnetic radiation of an electron interacting with a laser pulse is studied. It is shown that this radiation is emitted in the form of extremely short attosecond pulses. It is found that an initially immobile electron does not move along figure-eight trajectories in the field of a linearly polarised laser pulse.
