Laser technology is known as one of the four major technological innovations of the 20th century, alongside atomic energy, semiconductors, and computers. The excellent characteristics of lasers, including their distinct monochromaticity, excellent coherence, and clear directionality, enable them to concentrate huge energy densities in extremely small areas, thus demonstrating enormous potential for application in the field of material processing. Since the birth of the world's first laser in 1960, laser technology has become a new favorite in the technology industry. In the 1970s and 1980s, laser marking technology, an emerging field of laser applications, emerged internationally and quickly received a warm response from the market, becoming an indispensable part of the laser processing industry.
