Abstract

Obturateur électro-optique ultrarapide. Il comprend un cristal électro-optique recevant un faisceau incident et pouvant le transmettre sous l'influence d'un champ électrique, une électrode étant disposée sur l'une de ses faces, un premier joint de silicium étant intercalé sur cette électrode et la divisant en deux parties, le champ électrique pouvant être créé par une tension appliquée entre l'une des parties de l'électrode et la face du cristal opposée à celle comportant l'électrode. L'invention est mise en oeuvre dans la technique du laser.
