PLASMA CONDITIONS FOR OPTIMUM GAIN IN RESONANT PHOTOEXCITATION OF STRONTIUM NEON-LIKE IONS BY ALUMINIUM RADIATION

J. Gauthier , J. Geindre , P. Monier , C. Chenais-Popovics

Resonant photoexcitation of strontium neon-like ions by the radiation of aluminium hydrogen-like ions is studied theoretically and experimentally in laser-created plasmas. X-ray and XUV spectroscopy are used as tools to define plasma conditions where photo-pumping is efficient. The design of targets is completed by ablation studies of strontium layers under various experimental conditions. Absorption spectroscopy in a two plasma experiment demonstrates the potential usefulness of quasi-resonant photoexcitation in neon-like X-ray amplifiers.
