Nous avons montré que plusieurs transitions des ions lithiumoides donnent naissance à des inversions de population qui se produisent au cours de la recombinaison de plasmas-laser /1/. La transition 3d-5f située à 105.7 Å a fait l'objet d'une étude détaillée qui révèle l'existence d'un gain passant par une valeur maximum d'environ 2 cm-1 près de 6 ns après le sommet de l'impulsion laser dont la durée est de 2 ns. Cette étude a été récemment étendue à la raie 3d-4f située à 154.7 Å et nous avons observé une valeur de gain similaire avec le même comportement temporel. De plus, en suivant des prévisions fournies par des calculs effectués pour des ions de Z plus élevé /2/, nous avons étudié la transition 3d-5f de S13+ située à 65.2 Å. Nous trouv...
