Abstract
A laser processing device includes a laser light source, a spatial light modulator, a control section, and a condensing optical system. The spatial light modulator, presents a hologram for modulating the phase of the laser light in each of a plurality of two-dimensionally arrayed pixels, and outputs the phase-modulated laser light. The control section causes a part of the phase-modulated laser light (incident light) to be condensed at a condensing position in a processing region as a laser light (contribution light) having a constant energy not less than a predetermined threshold X. The control section causes a laser light (unnecessary light) other than the contribution light condensed to the condensing position existing in the processing region to be dispersed and condensed at a condensing position existing in a non-processing region as a plurality of laser lights (non-contribution lights) having an energy less than the predetermined threshold.
