Abstract
Provided is a laser processing device capable of detecting that a return light of a laser light reflected by a processing object is incident on a laser light source. The laser processing device includes: a laser light source which outputs a laser light for processing; a light source for inspection which outputs a laser light for inspection having a wavelength different from that of the laser light for processing; an optical waveguide in which the laser light for processing and the laser light for inspection are incident from an incident surface, and the laser light for processing and the laser light for inspection are emitted from an emission surface toward a processing object; and a detector which detects a return light of the laser light for inspection reflected by the processing object, incident from the emission surface of the optical waveguide and emitted from the incident surface.
