(JA) 導光装置、導光方法、及びLDモジュール
Abstract:
(EN) In order to improve the reliability of an LD module without causing a decrease in the coupling efficiency of a laser diode and an optical fiber, this light guide device is mounted on an LD module (1), the light guide device having a division optical system (DM) that generates partial beam groups by dividing a laser beam, and a synthesis optical system (RM1, RM2, PRE, PBC) that synthesizes the partial beam groups and thus generates a partial beam bundle comprising a plurality of partial beams which have an S-axis parallel to a specific spatial axis.
(FR) Afin d'améliorer la fiabilité d'un module LD sans provoquer une diminution du rendement de couplage d'une diode laser et d'une fibre optique, ce dispositif de guide de lumière est monté sur un module LD (1), le dispositif de guide de lumière comportant un système optique de division (DM) qui génère des groupes de faisceaux partiels en divisant un faisceau laser, et un système optique de synthèse (RM1, RM2, PRE, PBC) qui synthétise les groupes de faisceaux partiels et génère ainsi un faisceau partiel comprenant une pluralité de faisceaux partiels qui présentent un axe S parallèle à un axe spatial spécifique.
(JA) レーザダイオードと光ファイバとの結合効率を低下させることなく、LDモジュールの信頼性を高める。LDモジュール(1)に、レーザビームを分割することによって部分ビーム群を生成する分割光学系(DM)と、上記部分ビーム群を合成することによって、S軸が特定の空間軸に平行な複数の部分ビームからなる部分ビーム束を生成する合成光学系(RM1、RM2、PRE、PBC)とを有する導光装置を搭載する。
