Abstract

The evolution of density profiles in picosecond laser plasmas have been inferred from frequency shifts of reflected probe laser beams. The frequency shifts are caused by two mechanisms: hydrodynamic expansion and ionization front motion. Both time-resolved expansion velocities and ionization rates are presented for plasmas produced by 1 0 Wcm2, 1 ps, 580 nm laser irradiation.
