Abstract
AbstractSurface plasmon (SP) based electron acceleration has been investigated during the interaction of short, ultra-intense (I > 1019 W/cm2) laser pulse with periodically modulated solid target. Laser contrast conditions are required to preserve the structural integrity of the target. Two dimensional (2D) particle-in-cell (PIC) simulations report emission of energetic (~ 78 MeV) electron bunches along grating surface for grazing incident of laser pulse at an optimum angle 4° with respect to target surface. The energy and flux of emitted electrons for grazing laser incidence were found to be strongly enhanced as compared to the incident angles satisfying the resonant condition for surface plasma wave’s excitation.
