Abstract

L'invention concerne un dispositif de génération d'impulsions laser amplifiées comportant au moins un laser impulsionnel piloté par au moins un moyen de déclenchement émettant un faisceau laser maître multiplexe spatialement en des faisceaux laser élémentaires qui sont amplifiés en parallèle par au moins deux amplificateurs optiques, chacun des faisceaux laser élémentaires amplifiés étant dirigé vers un volume de focalisation unique. Selon l'invention, chaque amplificateur (12) optique comporte une fibre à couches photoniques (2), au moins un moyen de pompage (3, 5) optique à diodes laser produisant au moins une onde de pompe (4) pour pompage longitudinal de ladite fibre et un moyen de focaliser (7) dans le volume de focalisation le faisceau amplifié (15) produit par la fibre, la fibre allongée en silice ou verre comportant un cœur dopé, le pompage de chaque amplificateur optique étant en continu et la génération des impulsions optiques amplifiées étant obtenue directement par le laser impulsionnel , ledit dispositif ayant une configuration du multiplexage, de l'amplification parallèle et de la focalisation de chaque faisceau permettant de garantir la synchronisation des impulsions optiques produites par l'ensemble des amplificateurs optiques à fibre afin qu'elles arrivent selon un séquencement temporel prédéterminé dans le volume de focalisation.
