1. A laser processing device is characterized by comprising:

  • a laser source that generates laser light;

    an optical transmission unit that transmits the laser light generated by the laser light source; and

    a processing head for condensing the laser beam transmitted by the optical transmission unit and irradiating the laser beam on the object to be processed,the optical transmission section has a plurality of cores, transmits laser light to the processing head by any of the plurality of cores,an ejection end of each of the plurality of cores facing the processing head is fixedly disposed in the processing head so as to be located close to a center line of the processing head,the laser processing apparatus further includes a switching unit that switches a core, which transmits the laser beam to the processing head, among the plurality of cores,the plurality of cores include two or more cores having different diameters, sectional shapes, and refractive indices,an ejection end of each of the plurality of cores facing the processing head is fixedly disposed in the processing head so as to be located at a position less than 1mm away from a center line of the processing head.
