Abstract
A laser processing device includes: a device frame; a support unit attached to the device frame and configured to support an object to be processed; a laser output unit attached to the device frame; and a laser converging unit attached to the device frame so as to be movable with respect to the laser output unit. The laser output unit includes a laser light source configured to emit laser light, and the laser converging unit includes: a reflective spatial light modulator configured to reflect the laser light while modulating the laser light; a converging optical system configured to converge the laser light at the object to be processed; and an imaging optical system constituting a double telecentric optical system in which a reflective surface of the reflective spatial light modulator and an entrance pupil plane of the converging optical system are in an imaging relationship.
