Abstract

A theoretical and experimental study of the dynamics of the electron density gradient in near-solid-density plasmas produced by the interaction of ultra-short laser pulses with solid targets at intensities between [formula omitted] and [formula omitted] [formula omitted] and pulse duration between [formula omitted] and [formula omitted] ps is presented. X-ray spectroscopy of [formula omitted] to [formula omitted] resonance and dielectronic satellite lines is used to determine the range of electron densities in the plasma. Frequency-domain interferometry is employed to measure the expansion velocity and the electron density gradient scale length as a function of laser pulse duration and intensity. Quantitative agreement is noticed with one-dimensional hydrodynamic simulations which include the solution of the wave equation for the laser field.
