Ultraviolet laser source marking is mainly used in the field of ultra-fine marking

Ultraviolet laser marking belongs to a kind of laser marking process. The principle is to use the laser beam to focus on the surface of various materials for marking processing. Thin, can achieve ultra-fine marking, the heat affected area is very small, the thermal effect is relatively small, and the problem of material scorching damage will not occur. Advantages, and can be applied to a wider range of materials.

Advantages of UV Laser Marking

Compared with the infrared laser, the ultraviolet laser belongs to the 355nm band, and adopts the third-order intracavity frequency doubling technology. The laser beam focusing spot is extremely small during ultraviolet laser marking, and the heat-affected area during processing is very small, which can be very good. It reduces the deformation probability of the marking material and is an ideal choice for fine processing. It is mainly used in the field of ultra-fine marking, such as food, pharmaceutical packaging material marking, circuit board marking, glass material marking and other application fields.

Most of the laser applications on the market now use laser generators in the infrared band, such as CO2, optical fibers, semiconductors and discs. In addition, green light and ultraviolet light are also included. Among them, the infrared laser processing technology is currently the most mature. The type of laser processing has been widely used in industry, but the market potential of green laser and ultraviolet laser is also very large. At present, it has not been fully exploited, especially the technology and market development of ultraviolet laser. potential.

Ultraviolet laser marking is often used for ultra-fine marking of special materials, and is the first choice for customers who have higher requirements for marking effects. The high-energy molecules of ultraviolet photons in the ultraviolet laser processing process directly act on the surface of the workpiece to be processed, and quickly complete the detachment of the molecules on the metal or non-metallic materials. The heat generated by this working method is very small, which is also different from traditional laser applications. one.

The effect of UV laser marking and processing of product materials is better, with clear patterns and fine textures. When using UV laser processing, the probability of mechanical impact on materials is reduced to 1%, and its fine processing, stable quality, and processing effect. The advantages of good processing will be better presented. I believe that in the future laser market, ultraviolet lasers will usher in more technological breakthroughs and industrial applications.
