Purpose: of this paper is to study the acceleration of the charged particles by the laser beam in the range outside the resonance conditions. The studies have been limited in the subresonance region since in order to achieve the resonance acceleration a very high constant magnetic field is needed. Design/methodology/approach: The studies are carried out using the analytical derivations of the particles dynamics and its kinetic energy. The evolution of the acceleration process in time has been studied. The presented illustrations enabled interpretation of the obtained equations. Findings: The kinetic energy of the particle periodically achieves the maximal energy. Its value and the distance between the subsequent maxima rise with the increasing magnetic field or the laser beam intensity. However, these parameters of oscillating energy decrease with the decreasing wavelength. Research limitations/implications: Limits in the energy of accelerated particles are caused by the limits of the available at present the laser beam energy and the static magnetic field intensity. Practical implications: The authors of this paper believe that the presented results of the studies will help the designing of the experimental studies. It has been shown the way of achieving the high energy particles without the application of a very high magnetic field. Originality/value: The value of the paper is the analytical derivation of the parameters describing the oscillatory shape of the particles energy and numerical analysis its course. According to the authors best knowledge there are no performed such analysis of the acceleration process.
