Spectral diagnostic of a resonantly laser created non-Debye plasma
The time history of electronic density and temperature is a main point of the study of a resonantly laser created (weakly non-ideal) plasma. In order to carry out this study, with the aim of explaining the unusual variations of the emitted 4D→3P and 4F→3P Na(I) lines intensity, the authors perform a Star calculation (including ion-dynamic effect) and use as a diagnostic a comparison between experimental and theoretical profiles. Good agreement is obtained for most of the records. As for the Na 3P-level population, its time history is close to those already obtained in other studies, with different experimental conditions but for comparable densities L'evolution de la densite electronique et de la temperature est un point essentiel de l'etude d'un plasma (faiblement non ideal) obtenu par resonance laser. Afin d'effectuer cette etude, dans le but d'expliquer les variations inhabituelles observees, de l'intensite des raies 4D→3P et 4F→3P de Na(I), les auteurs utilisent un calcul de perturbation Stark (tenant en compte d'un effet dynamique des ions) et basent leur diagnostic sur la comparaison entre les profils experimentaux et theoriques. Un bon accord est obtenu dans la majorite des cas. Quand a la population du niveau 3P, son evolution est a rapprocher de celle deja mise en evidence par d'autres travaux, dans des conditions experimentales differentes mais pour des densites proches
