Recent experiments at KMS have been performed to investigate parameter variations of target component thickness, laser pulse duration and intensity, and one-sided vs two-sided irradiation in order to optimize the performance of the Livermore exploding foil selenium x-ray laser experiments. Preliminary experiments with selenium double foil targets were also conducted as a means of prolonging the duration and enlarging the spatial extent of the lasing conditions. Four-frame holographic interferometry was used in determining the time-dependence of densitiy profiles obtained by Abel inversion of the interferometric fringe field and comparisons were made to LASNEX code calculations.
