  • Publication number: 20190353857
    Abstract: A condenser lens for collecting a laser beam (300) is disposed between the laser oscillator and the incident end surface of the optical fiber. The laser beam (300) is divided into a plurality of beams (303, 304). The power of the laser beam (304) is measured and maximized by adjusting the position of the condenser lens. The FFP of the laser beam (303) is measured and minimized by adjusting the position of the condenser lens. These adjusted positions are stored as the first and second lens positions. The FFP of the laser beam (303) is measured while the condenser lens is being moved between these positions so as to make the BPP not more than a predetermined value.

  • Publication number: 20190293873
    Abstract: There is provided an optical axis alignment mechanism between the laser oscillator and the optical fiber. The laser oscillator emits laser light, which then emerges from the emission end of the optical fiber via the axis alignment mechanism. Part of the laser light is received on the light-receiving surface of the CCD camera of a laser light evaluator. Thus, the laser light evaluator acquires a light intensity distribution. The light intensity distribution is used by the optical axis alignment mechanism to align the axis of the laser oscillator with the axis of the optical fiber.
