Abstract

Of interest is a solution of the equation of motion of a charged particle in the field of amplitude-modulated electromagnetic waves in order to investigate the interaction of high-intensity laser pulses with solid targets in relation to the practical development of multifrequency lasers and the development of the technology of laser modulation. The reason for this study is due to the wide practical application of high-temperature plasma formed on the surface of the target and the search for new modes of interaction of the laser plasma. Powerful laser pulses are currently being used as an effective tool for the collective acceleration of charged particles, producing high-energy particles by exposing the target to a thin foil. Objective. An analysis of the motion of a particle in an electromagnetic field, analysis of the modulated amplitude oscillations in the case of circular polarization of the radiation, and the derivation of the formulas for the mean kinetic energy of the particle. Presented in this paper are the exact solutions of equations of motion for a charged particle in a flat amplitude-modulated wave, as in the case of circular polarization, and the expressions for the average kinetic energy of the particle. The results obtained can be used for the interpretation of experiments with plasma in an external magnetic field.

Keywords:
