Abstract

Taking the TEM 1 , 0 -mode Hermite–Gaussian (H–G) beam as a numerical calculation example, and based on the method of the perturbation series expansion, the higher-order field corrections of H–G beams are derived and used to study the electron acceleration by a tightly focused H–G beam in vacuum. For the case of the off-axis injection the field corrections to the terms of order f 3 ( f = 1 k w 0 , k and w 0 being the wavenumber and waist width, respectively) are considered, and for the case of the on-axis injection the contributions of the terms of higher orders are negligible. By a suitable optimization of injection parameters the energy gain in the giga-electron-volt regime can be achieved.
