| 英文摘要 | PURPOSE:To easily position a semiconductor laser chip and an input lens on an optical axis by disposing an input lens mounting and supporting member by inserting the columnar protrusion of a heat sink member into a slotlike mounting hole in a state that it is brought into contact with the hole at two positions in its radial direction. CONSTITUTION:A semiconductor laser chip 34 is fixedly mounted on a heat sink member 38, an input lens 40 is mounted on a mounting and supporting member 42, a columnar protrusion 46 protrudes from the member 38, and slotlike mounting hole 48 is formed at the member 42 in a state that the protrusion 46 is so inserted into the holes that it is brought into contact with the holes at two radial positions. The member 42 is displaced longitudinally of the member 38, longitudinally of the hole 48 and circumferentially of the protrusion 46 to position the chip 34 and the lens 40 on an optical axis, and the protrusion 46 is, after the positioning, physically secured, for example, by soldering or laser welding to the member 42 in the hole 48. |
