Abstract
A laser machining deviceincludes a laser light source, a spatial light modulator, a controller, a converging optical system, and a shielding member. The phase-modulating spatial light modulatorinputs a laser beam outputted from the laser light source, displays a hologram modulating a phase of the laser beam at each of a plurality of pixels arranged two-dimensionally, and outputs the phase-modulated laser beam. The controllercauses the spatial light modulatorto display a plurality of holograms sequentially, lets the converging optical systemconverge the laser beam outputted from the spatial light modulatorat converging positions having a fixed number of M, selectively places N converging positions out of the M converging positions into a machining region, and machines an object to be machined
