Abstract
Provided are a method and a device for adjusting an optical axis of laser light, capable of accurately grasping change in the state of the laser light and maintaining the quality of laser processing. The method for adjusting an optical axis of laser light includes: a step of detecting a position of laser light by position sensitive detectors arranged at two or more detection positions on an optical path of the laser light that is output from a laser light source toward a workpiece; and a step of adjusting, based on the detected position of the laser light, at least one of a position and an angle of optical elements arranged at two or more positions on the optical path of the laser light, to adjust an optical axis of the laser light.
