A transmissive liquid crystal cell to which pattern information of a mark to be engraved is given from the outside, and linearly polarized laser light emitted from a laser light source in the wavelength range from visible wavelengths to near-infrared wavelengths. a laser marker comprising means for irradiating the transmissive liquid crystal cell with a laser beam, a forced cooling means for the transmissive liquid crystal cell, and an optical system for forming an image of the laser beam transmitted through the transmissive liquid crystal cell on a surface to be processed. In the above, a transmission type liquid crystal cell is used in which a two-terminal nonlinear element or a three-terminal active element is used as a driving method of the transmission type liquid crystal cell, and a laser reflective film is formed on at least the laser irradiation surface side of each element. A laser marker featuring 2. The transmissive liquid crystal cell in which the laser reflection film is formed on the laser irradiation side of at least one of the two-terminal nonlinear element or the three-terminal active element and a scanning line or signal line that transmits a potential/signal to each element. A laser marker according to claim 1 of the utility model registration, characterized in that the laser marker is used. 3. The laser marker according to claim 1, which is characterized by using the transmissive liquid crystal cell in which a laser light reflecting layer is provided in an area other than the liquid crystal operating range. 4. The laser marker according to claim 1, wherein the material of the laser light reflecting film is a metal thin film or a multilayer dielectric layer.
