The Origin And Development of Laser Marking Technology for Jewelry

 The laser marking process originated from the development of laser technology in the 1960s and was initially mainly used for marking simple text and patterns in the industrial field. In 1960, American scientist Maiman developed the world's first ruby laser, laying the foundation for laser marking technology. Since then, laser technology has continued to develop, and related equipment and processes have gradually been improved.

 By the late 1970s and early 1980s, laser marking began to develop as a new processing technology. With the advancement of laser technology, computer technology and the improvement of optical devices, its application scope gradually expanded.

 In 1999, Ann Marie Carey realized the application of laser color marking technology in craft metal products and jewelry, making laser color marking practical in the jewelry field. Since then, the application scope of jewelry laser marking technology has continued to expand.

 With the continuous advancement of technology, the laser marking process for jewelry is developing towards greater precision, efficiency and personalization. Nowadays, this process can use ultraviolet laser marking machines to achieve extremely fine engraving on the surface of precious metals, with a line width of up to 0.05mm. It can also perform invisible marking inside gemstones such as diamonds to add anti-counterfeiting codes and other information, without affecting the aesthetic appearance of the jewelry. Meanwhile, the laser marking process, in combination with fixtures and visual positioning systems, can achieve batch automatic marking, enhancing production efficiency and better meeting the production demands of the jewelry industry.
