The ultraviolet laser marking machine is developed by 355nm ultravioletlaser . Compared with the infrared laser , the third-order intracavity frequendoubling technology

adopted in the machine can directly break the molecular chain of the material by short wavelength laser , greatly reducing the mechanical deformation of the material .

Although it is heated , it is cold light .

It is mainly used for superfine marking and engraving , especially suitable formarking and microporous of food and medicine packaging materials ( suchas plastics ) , high-speed division of glass and porcelain materials , and com -plex pattern cutting of silicon wafer
