Abstract

PRECIS DE LA DIVULGATION:

Système optique antiretour comporte un nombre N de lames à faces parallèles en un matériau ayant une constante de Verdet et des moyens pour créer un champ magnétique traversant les faces de ces lames. La première lame est orientée par rapport à un faisceau laser incident de manière que l'angle d'incidence soit égal à
l'angle de Brewster. Ce système est caractérisé par le fait que les plans des diverses autres lames sont orientés de telle sorte que l'angle d'incidence du faisceau reçu sur une lame soit voisin de l'angle de Brewster et que, d'autre part, la normale au plan d'une lame fasse avec la normale au plan de la lame située en amont, un angle égal à l'angle dont a tourné le vecteur polarisation de la lumière à la traversée de la lame amont en raison de l'effet Faraday. Le nombre des lames, le matériau qui les constitue, leur épaisseur et l'intensité du champ magnétique sont choisis de manière que la rotation totale subie par le vecteur de polarisa-tion de la lumière entre l'entrée du système et la sortie soit voisin de 45°.
