Paper Abstract

We propose to use an intense short pulse laser of the TEM(1,0)+TEM(0,1) mode in vacuum in order to trap and accelerate an electron bunch. The laser intensity distribution serves a confinement effect for electrons in the transverse direction by a transverse ponderomotive force. The electrons are accelerated longitudinally by a longitudinal ponderomotive force. In our computations, we employ a three-dimensional laser field and the relativistic equation of motion including a relativistic radiation damping effect. The maximum electron energy is about 195 [MeV] with an acceleration gradient of 5.25 [GeV/m] at the laser intensity of 1.23 x 1018 [W/cm2]. An emittance of the electron bunch accelerated is small and the spatial size in the radial and longitudinal directions are about 1000 [μm] and [μm], respectively. Such the electron bunch may have potentials for nano-technology applications, cancer treatment, a new point light source and so on.
