Essential differences in properties of fast ion flux from the interaction of 1 ps and 0.5 ns laser pulses with Au target have been observed.In short-pulse case, only a single fast ion group with a small angular divergence is generated and ions are likely to be accelerated by an axial ponderomotive froce from the skin-layer interaction. In the long-pulse case, at least two groups of fast are emitted into a wide solid angle.
