Abstract
El sistema láser totalmente de fibra de ultra alta potencia divulgado está configurado con múltiples láseres de fibra separados que producen haces de láser respectivos en trayectorias respectivas. El sistema divulgado está configurado además con un paquete de fibras cónico que incluye al menos una fibra de guía central y una pluralidad de fibras de guía periféricas. El sistema divulgado tiene además una fibra de entrega multicapa configurada con una sección transversal de cuello de botella doble y provista de al menos dos núcleos interior y exterior concéntricos y separados radialmente. El núcleo interior se acopla a las fibras de guía periféricas mientras que el núcleo interior se empalma con la fibra de guía central de modo que una salida del sistema emitida desde el núcleo interior de la fibra de entrega tenga una forma de haz diferente de la salida del sistema emitida desde el núcleo exterior.
