LASER OPTICAL PATH SWITCHING DEVICE

摘要

PROBLEM TO BE SOLVED: To make possible precisely switching an optical path of laser light to one among plural optical fibers in a short time by a simple device. SOLUTION: This device is provided with a reflection mirror 13 reflecting along the optical path of the laser light 18 from a laser oscillator 11, a lens 14 provided in the optical path of the laser light 18 reflected by the reflection mirror 13, an optical fiber holder 34 holding the end parts of plural optical fibers 33 and a moving means 16 movably supporting the optical fiber holder 34 and matching any one end part among plural optical fibers 33 with the laser light 18 converged by the lens 14. In such a case, the optical fiber holder 34 is moved by bite moving means 16, and any one end part among plural optical fibers 33 is matched with the laser light 18 converged by the lens 14.
