Which is better CO2 or fiber laser?

The difference between co2 laser marking machine and fiber laser marking machine

1. Different laser wavelengths

The co2 laser marking machine is 10.64 microns, and the fiber laser marking machine is 1064 nanometers, which is much shorter than the co2 model.

2. The working principle is different

co2 laser marking machine: using co2 gas as the medium for generating laser, high voltage is applied to the electrode, and a glow discharge is generated in the discharge tube, causing the gas molecules to release the laser, and the laser energy is amplified to form a laser beam for material processing .

Fiber laser marking machine: The laser is output directly from the fiber.

3. Different marking ranges

The co2 laser marking machine is mainly used in non-metal, PVC, ABS, PMMA glass, wood, paper, etc., and the price is cheap.

Fiber laser marking machine: the absorption of metal is better. It can be applied to various metals and some non-metals, electronic separation components, mobile communication, and hardware products. Knives and kitchen utensils, precision instruments, glasses and clocks. Computer keyboards, auto parts, plumbing/bathroom accessories. Fine marking, power saving, maintenance-free, and high price.

4. Different service life

The service life of the fiber laser marking machine is 10w hours, and the co2 laser marking machine is 3w hours.

5. Different precision

The precision of fiber laser marking machine is higher than that of CO2 marking machine.
