摘要	To increase the reliability of an LD module without decreasing the efficiency of coupling between the laser diode and the optical fiber, an LD module (1) includes a light-guiding device mounted therein that includes (i) a dividing optical system (DM) configured to divide a laser beam so as to generate a partial beam group and (ii) a compositing optical system (RM1, RM2, PRE, PBC) configured to composite the partial beam group so as to generate a partial beam bundle including a plurality of partial beams each having an S axis parallel to a particular spatial axis.
其他摘要	为了在不降低激光二极管和光纤之间的耦合效率的情况下提高LD模块的可靠性，LD模块（1）包括安装在其中的光导设备，其包括（i）配置的分割光学系统（DM）分割激光束以产生部分光束组和（ii）合成光学系统（RM1，RM2，PRE，PBC），其被配置为合成部分光束组以产生包括多个部分光束的部分光束。每个梁具有平行于特定空间轴的S轴。
主权项	A light-guiding device, comprising: a dividing optical system configured to divide a laser beam so as to generate a partial beam group consisting of a plurality of partial beams having respective traveling directions different from each other; and a compositing optical system configured to composite the partial beam group so as to generate a partial beam bundle consisting of a plurality of partial beams each having an S axis parallel to a particular spatial axis, the partial beam bundle having an S-axis diameter smaller than an S-axis diameter of the laser beam.
