Title (EN) OPTICAL DEVICE AND LASER DEVICE
(FR) DISPOSITIF OPTIQUE ET DISPOSITIF LASER
(JA) 光デバイス及びレーザ装置
Abstract:
(EN) This optical device comprises: a first fiber 31 having a core 31a and cladding 31b that surrounds the outer periphery of the core 31a, a second fiber 32 having a core 32a and cladding 32b that surrounds the outer periphery of the core 32a and having one end face 32fb connected to one end face 31fa of the first fiber 31, and a quartz block 35 connected to the other end face 32fa of the second fiber 32. The other end face 32fa of the second fiber 32 is smaller than the face 35fb of the quartz block connected to the second fiber 32, and larger than the one end face 31fa of the first fiber 31.
(FR) Ce dispositif optique comprend : une première fibre 31 ayant un noyau 31a et une gaine 31b qui entoure la périphérie externe du noyau 31a, une seconde fibre 32 ayant un noyau 32a et une gaine 32b qui entoure la périphérie externe du noyau 32a et ayant une face d'extrémité 32 fb reliée à une face d'extrémité 31 fa de la première fibre 31, et un bloc de quartz 35 relié à l'autre face d'extrémité 32 fa de la deuxième fibre 32. L'autre face d'extrémité 32 fa de la deuxième fibre 32 est plus petite que la face 35 fb du bloc de quartz relié à la deuxième fibre 32, et plus grande que la face d'extrémité 31 fa de la première fibre 31.
(JA) コア31a及びコア31aの外周を囲うクラッド31bを有する第1ファイバ31と、コア32a及びコア32aの外周を囲うクラッド32bを有し、第1ファイバ31の一方の端面31faに一方の端面32fbが接続される第2ファイバ32と、第2ファイバ32の他方の端面32faに接続される石英ブロック35と、を備える第2ファイバ32の他方の端面32faは、第2ファイバ32が接続される石英ブロック35の面35fbより小さく、第1ファイバ31の一方の端面31faより大きい。
