Laser Marking Machine
Fiber laser marking machine uses a fiber laser to hit the laser beam on the surface of various materials, and the surface material can undergo physical or chemical changes through light, so as to engrave permanent marks such as patterns, trademarks and texts. Its components include: fiber laser, laser galvanometer, field mirror, industrial computer, display, cabinet, control switch, power supply, ruler and lifting shaft, etc. MOPA laser marking machine also belongs to the type of fiber laser marking machine.
CO2 Laser Marking Machine
Carbon dioxide laser marking machine (CO2 Laser Marking Machine) uses a gas laser with an infrared light band of 10.64 μm, and charges CO2 gas into a high-voltage discharge tube to generate a glow discharge, so that the gas molecules emit laser light, and the laser energy is amplified to form a pair of laser beams. The laser beam for material processing, the laser beam vaporizes the surface of the processed object to achieve the purpose of engraving.
The differences between optical fiber and carbon dioxide laser marking machine are as follows:
- Different lasers: fiber laser marking machine adopts fiber laser, and carbon dioxide laser marking machine adopts CO2 gas laser.
- Different laser wavelengths: the laser wavelength of the fiber marking machine is 1064nm, and the laser wavelength of the carbon dioxide laser marking machine is 10.64μm.
- 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.
