Résumé. 2014 Des expériences récentes ont montré que certains effets en optique non linéaire pouvaient être augmentés dans les cristaux 43 m comportant des mâcles désorientées les unes par rapport aux autres. Ceci résulte de l’additivité de la puissance optique non linéaire générée dans les divers domaines de l’échantillon. Pour des mâcles espacées au hasard, l’accroissement est propor-tionnel au nombre de plans de mâcles N, alors que si l’espacemen est constant la variation suit une loi en N2. On discutera les avantages potentiels en optique non linéaire des cristaux de CdTe, ZnTe et ZnSe présentant ce type de mâcles. On donnera des critères en vue de déterminer le meilleur espacement des mâcles et on discutera les possibilités d’emploi de...
