Zusammenfassung:A laser processing machine to perform laser processing by focusing a laser beam onto a workpiece, includes a light-focusing optical system to focus the laser beam, wherein the light-focusing optical system has an aberration, and a lateral aberration with respect to a laser beam diameter: D86.5 containing 86.5% of the laser power of a laser beam before being focused is 0.2 mm or more, the lateral aberration being at a light focusing point relative to a light beam corresponding to the laser beam diameter: D86.5.
