Do you know these advantages of 355nm uv dpss laser marking?

Ultraviolet laser marking belongs to a kind of laser marking process. To achieve fine marking, the heat affected area is small, the thermal effect is relatively small, and the problem of material scorching will not occur. Wide range of materials.

Advantages of 355nm uv dpss laser Marking

Compared with the infrared laser, the ultraviolet laser belongs to the 355nm band, and adopts the third-order intracavity frequency doubling technology. When the ultraviolet laser is marked, the focused spot of the laser beam is small, and the heat affected area during processing is small, which can reduce the marking material. It is mainly used in the field of fine marking, such as food, 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, etc.

Ultraviolet laser marking is often used for fine marking of special materials, and it is recommended for customers who have higher requirements on the marking effect. The high-energy molecules of ultraviolet photons in the ultraviolet laser processing process directly act on the surface of the workpiece to be processed to complete the detachment of the molecules on the metal or non-metallic materials. This way of working generates less heat, which is also one of the differences from traditional laser applications.

Ultraviolet laser marking processing products have clear material patterns and fine textures, and its fine processing, stable quality, and other processing advantages
