摘要：
Comparative study of electron acceleration by linearly polarized (LP) and circularly polarized (CP) Hermite-cosh-Gaussian lasers in vacuum has been analyzed. Hermite-cosh-Gaussian profile is a special kind of Gaussian profile whose decentered parameter (b) plays a crucial role in the electron acceleration. It has been observed that the electron energy enhancement for CP laser pulse is much higher as compared to LP laser pulse for optimized values of laser parameters like laser intensity parameter (a0), laser spot size (r0), etc. It is seen from the results that maximum electron energy gain increases rapidly with the increase in the value of decentred parameter for CP laser. The electron enhances more rapidly with propagation distance z for CP laser pulse. This energy enhancement persists continuously for the successive increment of the laser spot size (r0) and b. The laser mode index is also responsible for the electron energy enhancement. The plotted graphs also reveal that the energy enhancement is higher for CP laser pulse as compared to LP laser pulse for different parameters.
