2014 Le montage décrit permet de stabiliser à ± 1 % la puissance transportée par un faisceau laser. Les fluctuations de l'intensité lumineuse sont compensées par des variations asservies de la transparence d'un cristal de KDP placé entre deux polariseurs parallèles.Abstract. 2014 A device allowing a relative stability of about 1 % of the laser beam power is described. The fluctuations of light intensity are servo-compensated by varying the transparency of a KDP crystal between parallel polarizers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
