[0002] Laser marking is an emerging processing technology that uses a beam of high-energy-density laser to interact with the surface of an object, causing physical or chemical changes on the surface of the object, thereby leaving a permanent mark on the surface of the object. As a modern precision processing method, laser marking has unparalleled advantages over traditional processing methods such as printing, corrosion, electrospark machining, and mechanical scribing. Laser marking is controlled by a computer and can mark various texts, symbols, and patterns on the surface of an object. It can also be easily designed and changed through software, which can greatly improve processing efficiency and meet the requirements of high efficiency and fast pace of modern production.
