Abstract
The present invention relates to a method and an apparatus for fabricating a preform (1,10,100) that can be used for drawing an active optical fiber (8). The present invention further relates to an active optical fiber (8), designed for amplification or attenuation purposes, drawn from said preform (1,10,100) and to an optical amplifier (600, 601) using a laser active optical fiber.
