ABSTRACT:
Optical paths of laser beams generated from at least two laser beam generators, which are used for performing connection and cutting work at prescribed locations of structural members, are each switched by corresponding optical path switchers, and the laser beams polarized by the corresponding optical path switchers are reflected in the same direction by a laser beam combiner to combine the plurality of laser beams into a parallel laser beam bundle, in order to perform cutting or welding at the corresponding prescribed location. This configuration removes the need to provide high-power laser beam generators for situations such as vacuum walls of fusion devices where the laser generation efficiency is low, while also making it possible to use more powerful high-power lasers therein if necessary.
