Abstract

L'invention concerne un obturateur électro-optique. Cet obturateur comporte une plaque diélectrique 12 entourant un cristal 1 électro-optique et deux électrodes 2, 5 appliquées sur les faces de la plaque, une des électrodes 5 étant commutable. L'épaisseur de la plaque et la largeur de l'électrode commutable croissent des deux extrémités de la plaque vers le cristal. Application à l'obturation de faisceaux laser.
