The UV laser marking machine is developed by using a 355nm UV laser. This machine uses a third-order intracavity frequency doubling technology. Compared with infrared lasers, the 355nm UV laser has a very small spot, and the marking effect is directly interrupted by a short-wavelength laser. The molecular chain greatly reduces the mechanical deformation of the material. Thermal deformation (cold light), because it is mainly used for ultra-fine marking and engraving. It is especially suitable for applications such as marking, micro-hole drilling of food and pharmaceutical packaging materials, high-speed dicing of glass materials, and complex pattern cutting of silicon wafers.
