Method of manufacturing optical medium

摘要

In a method of manufacturing an optical medium, an extended optical conductor containing active substance is formed to a predetermined shape by the use of resin by repeatedly folding or winding the optical conductor. A laser light beam or an amplified light beam is outputted from an edge portion of the optical conductor by absorbing an excitation light beam incident from the side surface of the optical conductor into the active substance through the resin. Thermoplastic resin is used as the resin. The thermoplastic resin transmits the excitation light beam. The resin is heated up to a glass transition temperature or higher. The optical conductor and the resin are bonded to each other so as to constitute a predetermined shape. The resin is cured.
