Abstract
A laser processing apparatusincludes a laser light source, a phase modulation type spatial light modulator, a driving unit, a control unit, and an imaging optical system. The imaging optical systemmay be a telecentric optical system. A storage unitA included in the driving unit stores a plurality of basic holograms corresponding to a plurality of basic processing patterns and a focusing hologram corresponding to a Fresnel lens pattern. The control unitarranges in parallel two or more basic holograms selected from the plurality of basic holograms stored in the storage unitA, overlaps the focusing hologram with each of the basic holograms arranged in parallel to form the whole hologram, and presents the formed whole hologram to the spatial light modulator
