Abstract: | We review recent PIC simulation results which show that double-sided irradiation of a thin over-dense plasma slab with ultra-intense
laser pulses from both sides can lead to sustained comoving Poynting flux acceleration of electrons to energies much higher
than the conventional ponderomotive limit. The result is a robust power-law electron momentum spectrum similar to astrophysical
sources. We discuss future ultra-intense laser experiments that may be used to simulate astrophysical particle acceleration. |
