摘要：

The evolution of density profiles in plasmas produced by 10(14)-W cm-2, 1-ps, 580-nm-wavelength laser pulses has been determined from spectral shifts imposed on a reflected picosecond probe pulse. The shifts are caused by two mechanisms: hydrodynamic expansion and ionization front motion. Both time-resolved expansion velocities and ionization rates are inferred from the spectral shifts and are compared to one-dimensional hydrodynamic simulations.
