Abstract

UNA FIBRA OPTICA PARA USAR EN LASERES DE FIBRA TIENE EL ADITIVO DE LASER, POR EJEMPLO, ER3+, CONCENTRADO EN EL CENTRO (13) DEL NUCLEO (14). PREFERIBLEMENTE, EL NUCLEO (14) TIENE UNA REGION INTERIOR (13) QUE CONTIENE EL ADITIVO, Y UNA REGION EXTERIOR (12) QUE ESTA LIBRE DE DOPANTE. LA CONCENTRACION DE DOPANTE DISMINUYE EL HUMBRAL DE BOMBEO PARA UN LASER Y MEJORA LA ACCION DE LA GANANCIA PARA UNA POTENCIA DE BOMBEO DADA. LA FIBRA SE HACE CONVENIENTEMENTE DE MCVD. EL USO DE AL2O3 EN LA ZONA PARECE DISMINUIR LA PERDIDA DE DOPANTE DURANTE EL COLAPSO DEL TUBO.
