Summary:There is provided a technique that enables efficient and uniform laser marking. A laser marker includes a laser light source, an illumination optical system, a spatial light modulator, a projection optical system, and a scanning unit. The laser light source emits laser light. The illumination optical system shapes the laser light into a line-shaped parallel beam. The spatial light modulator includes a plurality of modulation components arranged along a long-axis direction, and modulates the parallel beam into a line-shaped modulated beam using the plurality of modulation components. The projection optical system guides the modulated beam to an object. The scanning unit scans the surface of the object with the modulated beam.
