Quantitative Modeling of Electron Acceleration in Laguerre-Gaussian Laser Fields

Abstract

The use of Laguerre-Gaussian (LG) laser beams in particle acceleration provides a promising pathway for advancing laser-driven acceleration schemes. We investigate electron acceleration resulting from the interaction of LG beams with charged particles. A comprehensive theoretical framework is formulated to elucidate the underlying acceleration mechanisms, complemented by detailed numerical simulations. The electron dynamics in the structured electromagnetic fields of the LG beam are systematically analyzed, revealing distinctive acceleration behavior along the direction of beam propagation. Our results demonstrate that the orbital angular momentum and spatial field structure of LG beams enable controlled and efficient electron acceleration. These findings highlight the potential of LG beams as a viable tool for tailored electron acceleration and contribute to the broader development of advanced laser-plasma and laser-based acceleration techniques.
