Av. Kuznetsov et al., Efficiency of ion acceleration by a relativistically strong laser pulse inan underdense plasma, PLAS PHYS R, 27(3), 2001, pp. 211-220
A particle-in-cell simulation is used to investigate ion acceleration by a
femtosecond laser pulse propagating in an underdense plasma slab. In plasma
slabs with different thicknesses, the ions are found to be accelerated by
different mechanisms. It is shown that, for laser pulse intensities in the
range (5-10) x 10(19) W/cm(2), the ions are accelerated near the plasma-vac
uum interface. (C) 2001 MAIK " Nauka/Interperiodica ".
