| contents | A structure of a laser pulse may significantly influence the dynamics of interacting particles. In the case of dilute plasma the particle dynamics may be considered in the single particle approximation. In this paper the problem of the angular momentum gain of a single particle in a focused structured pulse is considered for some certain cases, including radial and azimuthal polarizations, in the frameworks of the theoretical model, presented in [E. Dmitriev and Ph. Korneev, 'Angular momentum gain by electrons under the action of intense structured light', Physical Review A, vol. 110, p. 013514, (2024)], which includes solving of Maxwell's equations with a required accuracy and the high order perturbation theory. The obtained analytical results are compared to the results of numerical simulations. Angular dependence in the structure of the laser pulse is shown to be critically important for the orbital angular momentum gain of an ensemble of charged particles in a structured wave. |
