Abstract
We report an analysis of absorption and fluorescence spectroscopy of the interaction of Al XIII Ly- radiation with Fe XXIV in laser-produced plasmas. These results were obtained in the context of exploring a Al-Fe photopumped X-ray laser scheme. Aluminium/iron targets were used in different geometries in order to observe in detail the transition mechanisms of the Al/Fe photopumping scheme. The absorption of the Al XIII Ly- emission by the Fe XXIV plasma was observed after traversing different lengths of an Fe plasma. A simple radiation transfer model is being developed as a post-processor to the 1-D hydro-code MED103 in order to simulate these results. We also report some experimental evidence that may indicate that enhanced fluorescence of Fe XXIV 5d-2p transition could have occurred due to photopumping by the Al radiation despite any direct evidence of photopumped XUV lasing.
