[Performances et limitations des sources à fibre dopée Er3+–Yb3+ de grande luminance]
Le développement récent des sources à fibres dopées permet d'atteindre des puissances crêtes élevées en régime impulsionnel. Les applications LIDAR à détection hétérodyne et à sécurité oculaire utilisent des amplificateurs à fibres optiques dopées erbium–ytterbium pour l'amplification de signaux de faible largeur spectrale. La principale limitation pour la montée en puissance est la Diffusion Brillouin Stimulée (DBS). Un modèle dynamique d'amplificateurs est présenté et comparé au modèle stationnaire de la source localisée non fluctuante. Il en résulte des règles d'architecture pour la conception de sources de forte brillance. L'accroissement de la taille du mode optique permet d'augmenter le seuil de la puissance d'apparition du phénomène DBS. Les fibres dopées guident alors plusieurs modes ce qui conduit à une dégradation de la qualité spatiale du faisceau émis. Une analyse détaillée de l'impact de la propagation multimode et des inhomogénéités du profil d'indice sur la qualité du faisceau est menée. Une source laser entièrement à fibre, conçue à partir des modèles présentés, a permis la génération d'impulsions d'énergie 100 μJ et 180 W crête.
Recent development of fiber sources allows the generation of high peak power in the pulsed regime. Coherent LIDAR applications in the eye-safe window are designed with erbium–ytterbium fiber amplifiers. The main limitation to increase the optical power of narrow linewidth signals is the Stimulated Brillouin Scattering (SBS). A dynamic model for these fiber amplifiers is presented, and compared to the stationary model of the non-fluctuating localized source. Design rules are deduced for high brightness power fiber amplifiers. Enlarging the optical mode size increases the SBS threshold. However, fibers can guide several modes leading to a decrease in spatial quality. A detailed analysis of multimode propagation and refractive index profile inhomogeneities and their influence on beam quality has been conducted. Our numerical model has been applied to the design of an all-fiber MOPA source generating 100 μJ per pulse with 180 W peak power.
