Laser marking technology is one of the application fields of laser processing.

Laser marking is a marking method that uses high-energy density laser to locally irradiate the workpiece, causing the surface material to vaporize or undergo a chemical reaction of color change, thereby leaving permanent marks. Laser marking can print various texts, symbols, and patterns, with character sizes ranging from millimeters to micrometers, which has special significance for product anti-counterfeiting. The extremely thin laser beam after focusing is like a tool, which can remove the material on the surface of the object point by point. Its progressiveness lies in that the marking process is non-contact processing, which does not produce mechanical extrusion or mechanical stress, so it will not damage the processed object; Due to the small size after laser focusing, the heat affected area is small, and the processing is fine, some processes that cannot be achieved by conventional methods can be completed.   

The "tool" used in laser processing is the focused light spot, which does not require additional equipment or materials. As long as the laser can work normally, it can be continuously processed for a long time. Laser processing is fast and cost-effective. Laser processing is automatically controlled by computers and does not require human intervention during production.   

The information that laser can mark is only related to the content designed in the computer. As long as the drawing marking system designed in the computer can recognize it, the marking machine can accurately restore the design information on a suitable carrier. Therefore, the functionality of software actually largely determines the functionality of the system.
