Résumé

We have shown that several transitions of Li-like ions give rise to population inversions during the recombination of laser-plasmas /1/. An extensive study has been made for the 3d-5f transition lying at 105.7 Å. It has shown a gain coefficient with a maximum around 2cm-1 occuring about 6 nanosecond after the top of the 2-ns laser pulse. We extended recently this study to the 3d-4f line ar 154.7 Å and we observed a similar value of gain with the same temporal behaviour. Moreover, following calculated predictions for higher-Z ions /2/, we studied the 3d-5f transition of S13+ which takes place at 65.2 Å. This study gives the first preliminary evidence of a gain coefficient of about 1 cm-1.
