Abstract
We present modelling results to interpret Li-like satellite spectra recorded from solid Al targets irradiated with ultra-short (80 fs), high intensity 1016-1017 W cm-2 laser pulses. A fully time-dependent, non-local thermodynamic equilibrium (NLTE) atomic kinetics model must be used to account for the observed satellite peak-intensity distribution; a stationary NLTE model is not sufficient. Hot electron effects on the doubly excited states population kinetics are also considered. Detailed Stark broadened line profiles are employed to compute the synthetic spectra. Modelling results indicate that the satellite emission is emitted in a 100 fs pulse.
