Abstract

We report an analysis of absorption and fluorescence spectroscopy of the interaction of Al XIII Ly-α 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-α 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.
