Abstract
This study investigates the phenomenon of electron acceleration produced by linearly polarized Hermite–cosh–Gaussian (HChG) laser pulse in vacuum. The effect of the normalized electric field amplitude (a₀), the decentered parameter of the cosh term (b), the Hermite mode index (s), the beam waist (r₀), and the initial normalized transverse velocity component (Vy) on the acceleration efficiency is investigated. The outcome of this study indicates that suitable adjustment of these parameters can improve in the energy absorption of electrons. Increasing laser electric field and appropriately selecting decentered parameter and Hermite polynomial mode index result in efficient acceleration. Laser beam waist (r₀) governs the confinement and focusing features of the laser electric field. Hermite–cosh–Gaussian laser can produce energy efficient electron acceleration in vacuum which can be utilized in the development of compact, laser-based particle acceleration technologies.
