LASER BEAM GENERATING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a laser beam generating device capable of collecting the laser beam injected from a plurality of beam injecting parts with an energy loss suppressed as much as possible. SOLUTION: The laser beam generating device 2 (2A) comprises an optical fiber unit 13 by position fixing a plurality of optical fibers 7a in a block with its beam receiving end surface 7b respectively opposed to the part corresponding to a plurality of beam injecting parts 11, and a positioning adjusting means 15 capable of adjusting the position of the beam injecting part 11 and the beam receiving end surface 7b to be opposed each other between a semiconductor laser unit 12 and the optical fiber unit 13. This can effectively collect the output laser beam from the semiconductor laser individually having a low power output to use a lase beam having a high power output for a laser machining.
