Abstract

LA LUZ DE BOMBEO, QUE SIRVE PARA AUMENTAR LAS SEÑALES DE LUZ DE AMPLIFICADORES OPTICOS Y QUE SE TRANSMITE POR LOS CONDUCTORES DE ONDA DE LUZ (4, 8), SE ALMACENA EN UNA PIEZA DE UN MATERIAL FIBROSO (3) AMPLIFICADOR DE LA SEÑAL DE LUZ, MEDIANTE UN ACOPLADOR DEL CONDUCTOR DE LA ONDA DE LUZ (5) Y PARA PODER ABSORBERSE COMPLETAMENTE, SE PUEDEN PRODUCIR INTERFERENCIAS EN EL TRAMO DE TRANSMISION. SEGUN LA INVENCION, SE COLOCA DETRAS DE LA PIEZA DE UN MATERIAL FIBROSO-AMPLIFICADOR DE LA SEÑAL DE LA LUZ (3), UNA PIEZA DE UN MATERIAL FIBROSO DE LA ABSORCION DE LUZ DE BOMBEO (7) QUE CONTIENE UN YTTERBIUM, QUE TIENE UN CORTE TRANSVERSAL DE ABSORCION MUY GRANDE EN EL CAMPO DE LA LONGITUD DE ONDA, DE 900 A 1050 NM, DONDE ESTA LA LONGITUD DE LA ONDA DE LA LUZ DE BOMBEO QUE PROVIENE DE UN LASER.
