Abstract
To provide a laser processing machine, a processing method, and a laser light source that are capable of miniaturization. The laser processing machine includes a laser light source and an optical system. The laser light source includes a light emitting body including a substrate and a bottom emission type vertical-cavity surface-emitting laser element that is provided on one surface of the substrate and emits an excitation light beam from another surface side of the substrate, and a cavity that is disposed in contact with the light emitting body on the other surface side of the substrate and oscillates a pulsed laser beam by incidence of the excitation light beam. The optical system causes the pulsed laser beam to contract and applies the pulsed laser beam to a workpiece.
