, DFZ-scan), qui procure en sortie un signal optique provenant essentiellement de la réfraction NL en présence d'une absorption NL modérée (q0 ? ??0 ? 1). L'acquisition expérimentale et la simulation numérique montrent un très bon accord et démontrent un gain en sensibilité 50 fois supérieur, Nous avons validé expérimentalement la nouvelle méthode Z-scan en champ sombre

, En bénéficiant de ces avantageuses propriétés, nous avons pu valider les mesures de n2 déjà effectuées à l'aide de la technique D4?-Zscan, confortant ainsi les résultats relatifs aux indices NL des Pphs qui peuvent être très disparates dans la littérature

, DFZ-scan peut aussi être une technique intéressante si elle est associée à un déplacement transversal 2D(x,y)
