Enhancing the Quality of Accelerated Electron Bunch Through the Circular Laguerre–Gauss Laser Pulses

This study examines the interaction of an electron bunch with a circularly polarized Laguerre–Gauss (LG) laser pulse. The distinct orbital angular momentum and intensity distribution of LG laser beams play a crucial role in their unique interactions with charged particles. The trajectory of the electrons is influenced by the interplay of the ponderomotive force and other forces acting on them. The energy of the electrons evolves over time, typically increasing rapidly during the interaction. The analysis suggests that the circular polarization of the LG laser pulse has advantages in terms of producing a more focused and energetic electron beam compared to linear polarization.
