Fiber laser marking machine is the use of fiber laser, the laser beam on the surface of a variety of different substances, through light energy to make the surface material physical or chemical changes, so as to carve out patterns, trademarks and text and other permanent marking equipment. Its components include: fiber laser, laser galvanometer, field mirror, industrial computer, monitor, cabinet, control switch, power supply, scale and lifting shaft, etc. MOPA laser marking machine is also a type of fiber laser marking machine.
Carbon dioxide laser marking machine using infrared wavelength 10.64μm gas laser, CO2 gas into the high voltage discharge tube to produce glow discharge, so that the gas molecules release the laser, the laser energy will be amplified to form the material processing of the laser beam, the laser beam to be processed surface gasification to achieve the purpose of engraving.
Ultraviolet laser marking machine using 355nm ultraviolet laser, the laser beam on the surface of a variety of different substances, through the short-wavelength laser directly interrupt the molecular chain of the substance, so as to carve patterns, trademarks and text and other permanent marking equipment.
The differences between optical fiber, carbon dioxide and ultraviolet laser marking machines are as follows:
1, the laser is different: fiber laser marking machine uses fiber laser, carbon dioxide laser marking machine uses CO2 gas laser, ultraviolet laser marking machine uses short-wavelength ultraviolet laser.
Ultraviolet laser is a very different technology from carbon dioxide and fiber laser technology, ultraviolet laser is also known as blue laser beam, the technology has a low heat engraving ability, it does not heat the surface of the material like fiber and carbon dioxide laser marking machine, belongs to cold light engraving.
2, the laser wavelength is different: the laser wavelength of the fiber marking machine is 1064nm, the laser wavelength of the carbon dioxide laser marking machine is 10.64μm, and the laser wavelength of the ultraviolet laser marking machine is 355nm.
3. Different application fields: CO2 laser marking machine is suitable for most non-metallic materials and some metal products engraving, fiber laser marking machine is suitable for most metal materials and some non-metallic materials engraving, UV laser marking machine can clearly mark all plastic and other materials that have adverse reactions to heat, Especially suitable for food, pharmaceutical packaging materials marking, punching microholes, high-speed division of glass materials and complex graphics cutting of silicon wafers and other applications.
