| 英文摘要 | PURPOSE:To improve an optical output, to adjust an optical axis easily and to enhance stability for a prolonged term by coupling laser beams from a first semiconductor laser and laser beams from a second semiconductor laser by a polarizing element and introducing the coupled laser beams to the same optical axis. CONSTITUTION:Laser beams F from a semiconductor laser 20 are changed into parallel beams by a convergent lens 22, and projected to a polarizing element 24. The direction H of polarized electromagnetic radiation of laser beams F and the direction I of polarized electromagnetic radiation of the polarizing element 24 run parallel, and laser beams F are hardly attenuated and pass through the polarizing element 24. Laser beams G from a semiconductor laser 21 are turned into parallel beams by a convergent lens 23, and projected to the polarizing element 24. The direction J of polarized electromagnetic radiation of laser beams G and the direction I of polarized electromagnetic radiation of the polarizing element 24 cross at right angles, and laser beams G are totally reflected approximately by the polarizing element 24. Reliability is not deteriorated as they are in optical outputs from each semiconductor laser 20, 21, an optical output at twice as much as optical outputs from the lasers 20, 21 is given, and laser beams K, optical axes thereof are aligned, are obtained. |
