とを特徴とするレーザマーカ。[Claims for Utility Model Registration] A transmissive liquid crystal to which pattern information has been applied from the outside is irradiated with linearly polarized laser light emitted from a laser light source, and the resulting transmitted light is separated into each polarized light component by a polarizing plate. In a laser marker that irradiates a workpiece with a laser beam that reflects the pattern information of a transmissive liquid crystal to imprint the pattern on the workpiece surface, among the polarized components separated by the polarizing plate,
A laser marker characterized in that the pattern detector is configured to receive a laser beam containing a polarized component that is not used for marking.
