La dépendance entre le champ électrique et l'écartement des franges du transfert d'énergie stationnaire entre deux faisceaux traçants lors de la formation en volume d'un hologramme de phase avec des matériaux photoconducteurs électro-optiques (KNbO3:Fe2+, Bi12(Si,Ge)O20,...) a été étudiée. Les résultats expérimentaux sont comparés avec les expressions théoriques décrivant l'influence de différents champs de charge-espace photoinduits dans des domaines photoréactifs. Un pic d'accroissement exponentiel Ɖ = 15 cm-1 a été atteint dans le cas de KNbO3:Fe2+ avec un choix approprié de paramètres expérimentaux (tels que l'enregistrement de la longueur d'onde, l'espacement des franges, champ électrique appliqué etc...). Les résultats de la dépendanc...
