Inversions de population lors de la création, par interaction laser résonnante, de plasmas complètement ionisés
Rate equations are investigated numerically. They evidence the importance at the beginning of ionization kinetics, of collisions between excited atomic species. Specially, energy pooling fills the 4D and 5S levels and consequently induces a strong population inversion. The transient inversion always takes place in the process which leads to complete ionization Un traitement numerique des equations d'evolution montre l'importance, pour le debut de la cinetique d'ionisation, des collisions entre especes atomiques excitees. En particulier, le processus d'«energy pooling» peuple fortement les niveaux 5S et 4D entrainant ainsi une forte densite d'inversion de population. Celle-ci apparait toujours mais de facon transitoire dans le processus qui conduit a l'ionisation complete
