Li-like satellite emission recorded in experiments involving the irradiation of solid Al targets with ultra-short (100 [ital fs]), high intensity (10[sup 17] [ital W] [ital cm][sup [minus]2]) laser pulses show a peak-intensity distribution which is inconsistent with the results obtained from a stationary, NLTE intensity model. A fully time-dependent NLTE atomic kinetics model must be used to account for the observed satellite peak-intensity distribution. We also consider hot electrons effects on the population kinetics of doubly excited states. Detailed Stark broadened line profiles are employed to compute the synthetic spectra.
