The difference between carbon dioxide and fiber laser marking machine

by:Leadtech Coding     2021-12-05

The carbon dioxide laser marking machine uses a gas laser with an infrared wavelength of 10.64μm to charge CO2 gas into the high-pressure discharge tube to generate glow discharge and release gas molecules After the laser is emitted, the laser energy is amplified to form a laser beam for material processing, and the laser beam vaporizes the surface of the processed body to achieve the purpose of engraving.

The difference between carbon dioxide and fiber laser marking machine is as follows:

1, the laser is different

The carbon dioxide laser marking machine uses a CO2 laser, and the fiber laser marking machine uses a fiber laser. The laser wavelength of carbon dioxide is 10.64μm, and the laser wavelength of fiber is 1064nm. Fiber lasers rely on optical fibers to conduct lasers, while CO2 lasers need to rely on an external optical system to conduct lasers. Therefore, CO2 lasers must be used before each equipment is used. The optical path is adjusted, and the fiber laser does not need to be adjusted.

2. Different application fields

CO2 laser The marking machine is suitable for engraving most non-metallic materials and some metal products, such as bamboo products, wood, acrylic, leather, glass, building ceramics, rubber and other non-metal products; fiber laser marking machine is suitable for most metal materials and Engraving of some non-metallic materials, such as engineering plastics, electroplating materials, spraying materials, plastic materials, rubber, epoxy ceramics, etc.

3. Some other differences

The longest service life of fiber laser marking machine can reach 100,000 hours. The longest service life of the carbon dioxide laser marking machine is 30,000 hours. In addition, the CO2 laser marking machine is more expensive when the laser power is the same.
