Abstract
A laser processing apparatus includes a spatial light modulator for inputting laser light output from a laser light source and outputting laser light after phase modulation by a hologram, and a control unit for presenting, on the spatial light modulator, the hologram for focusing the laser light after the phase modulation output from the spatial light modulator on a plurality of irradiation points in a processing object by a focusing optical system. The control unit sets at least one of a shape and a size of a processing region defined by the irradiation points in a first plane intersecting an optical axis of the laser light and a processing region defined by the irradiation points in a second plane intersecting the optical axis and separated from the first plane in a direction of the optical axis to be different from each other.
