    • A semiconductor laser is inserted into a first hole of a fixing member. An optical system including a cylindrical lens barrel and a lens attached inside the lens barrel is inserted into a second hole in order to direct a light beam emitted from the semiconductor laser to a predetermined position. The first and second holes are formed to be opposite to each other and are arranged on the same axis. The semiconductor laser and the optical system inserted into the first and second holes, respectively, so as to be partly exposed are fixed by laser welding at entrances of the first and second holes. The fixing member is provided with a third hole vertically penetrating the second hole. An adhesive is filled into the third hole. Further, an adhesive is applied onto laser welding points at the entrance of the first hole.
    • 将半导体激光器插入到固定构件的第一孔中。 将包括柱面透镜镜筒和安装在透镜镜筒内的透镜的光学系统插入到第二孔中,以将从半导体激光器发射的光束引导到预定位置。 第一和第二孔形成为彼此相对并且布置在同一轴线上。 通过在第一孔和第二孔的入口处的激光焊接固定分别插入第一孔和第二孔中以便部分暴露的半导体激光器和光学系统。 固定构件设有垂直贯穿第二孔的第三孔。 粘合剂填充到第三孔中。 此外,将粘合剂施加到第一孔的入口处的激光焊接点上。
