Abstract: The measurement of photoionization cross-sections offree ions or refractory atoms is difficult as asuitable absorbing column must be produced andbacklighted by a bright synchronized XUV-continuumemitting source. In the dual laser plasma (DLP)technique both the absorbing and backlighting plasmasare produced by the interaction of high-power laserbeams with suitable solid targets. The authors describesome recent results obtained with the DLP technique.With a single-laser system and photographic detection,inner-shell excitations from both ground and excitedstates in Al and Si species up to the fourth stage ofionization have been recorded. New and unexpectedresults were obtained for La$+3$PLU$/. By using aphotoelectric-based multichannel detector and asynchronized multilaser system, the versatility andreliability of the DLP technique is greatly improved.Time-resolved spectra have been obtained for atomic Crand Mn and their ions at photon energies between 40 and70 eV where the dominant absorption mechanism isexcitation of the 3p subshell. An intercomparison ismade between results obtained with the DLP method andcorresponding results recorded with alternativetechniques. Preliminary results for atomic tungsten andplatinum are shown.!
