摘要

A q-Gaussian laser pulse is used to explore the energy gain of electrons in vacuum, and important factors controlling this interaction are studied. The electron energy gain is shown to be strongly boosted by larger laser electric field amplitudes and to grow when the q-parameter, which determines the laser pulse profile, grows in value. Energy gain is further amplified by wiggler magnetic fields, and it is often reduced by greater wiggler wave numbers. Improving the beam waist is also shown to be an important factor for electron acceleration maximization. Under the optimized circumstances, the interaction of electrons with a 0.5 MeV energy level with a q-Gaussian laser pulse of intensity \(\:1.1\times\:{10}^{19}\:\) W/cm² results in the production of electrons with an energy level of 884.69 MeV. These results have important implications for developing more effective methods of advanced particle acceleration, such as laser-driven electron acceleration in vacuum.
