Abstract

La présente invention concerne une cellule de Pockels qui comporte un premier cristal présentant un effet de Pockels. La présente invention a trait à l'utilisation d'un second cristal, adapté en termes de dilatation thermique, pour modifier les fréquences de résonance acoustiques du premier cristal. Cette mesure permet de réduire une résonance piézoélectrique.
