Abstract: 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.

Abstract: A laser processing head apparatus with a camera monitor includes a light source for illumination having a near-infrared laser diode that generates a near-infrared laser beam of which upper limit value is a wavelength of a laser beam for processing, and out of processing point-emitted light, a processing point-reflected laser beam and illumination light for imaging, which have passed through a condensed lens and a laser beam reflection mirror and are directed to the camera respectively. An optical filter blocks transmission of the processing point-emitted light and the processing point-reflected laser beam, and transmits the illumination light for imaging.
