Title (EN) LIGHT SOURCE DEVICE AND PROCESSING METHOD
(FR) DISPOSITIF DE SOURCE DE LUMIÈRE ET PROCÉDÉ DE TRAITEMENT
(JA) 光源装置および加工方法
Abstract:
(EN) This light source device has a MOPA configuration, and is equipped with a seed light source, a pulse generator, and interim light amplifier, a final stage light amplifier, optical fiber for delivery, and a light output terminal. The optical fiber for delivery is a PBG fiber having a photonic band gap (PBG) structure in the core periphery area which is positioned around the core. Light having a wavelength within the high loss band of the PBG fiber is input into the PBGF.
(FR) L'invention concerne un dispositif de source de lumière possédant une configuration MOPA et comprenant une source de lumière de semence, un générateur d'impulsions, un amplificateur de lumière intermédiaire, un amplificateur de lumière d'étage final, une fibre optique pour l'émission, et un terminal de sortie de lumière. La fibre optique pour l'émission est une fibre PBG ayant une structure de bande interdite photonique (PBG) dans la zone de périphérie de l'âme qui est située autour de l'âme. La lumière ayant une longueur d'onde dans la bande de perte élevée de la fibre PBG est envoyée dans la PBGF.
(JA)  本発明は光源装置に関し、当該光源装置は、MOPA構成を有し、種光源、パルス発生器、中間光増幅器、最終段光増幅器、デリバリ用光ファイバおよび光出力端を備える。デリバリ用光ファイバは、コア周囲に位置するコア周辺部にフォトニックバンドギャップ(PBG)構造を有するPBGファイバである。PBGファイバの高損失帯域内の波長の光がPBGFに入力される。
