Fiber Laser VS CO2 Laser…Which Is Better?

- Apr 14, 2018-

In industrial laser cutting, there are two major technologies: fiber and CO2. Making the right choice is essential for high-speed, high productivity work, but the choice is more complex than it seems.

Fiber Laser

Fiber lasers are the newest development in laser cutting. The laser beam is created by an active fiber and transmitted over a transport fiber to the machine cutting head. Fiber lasers are significantly smaller than CO2 lasers and generate twice as much power from the same amount of current. A fiber laser cutting system is suitable to cut thin to medium-thick metal material. In other words, metal material thickness under 25mm, fiber laser cutting can get to a high precision and fast speed.

CO2 Laser

A CO2 laser uses a gas mixture to create the laser beam. The necessary high voltage in the resonator is created with the help of wear-free semiconductor excitation modules. The CO2 technology is suited for all-rounders who process various materials and thick sheet metal.

Advantage of Fiber Laser Compared with CO2 Laser

  • Excellent beam quality: focus light spot is smaller, cutting line is more precise, the work efficiency is higher, the processing quality is better.

  • Extremely high cutting speed: 2 times of the same power CO2.

  • High stability: the use of the world's top imported fiber laser, stable performance, the key components of the service life of up to 100 thousand hours.

  • High electro-optical conversion efficiency: fiber laser cutting machine photoelectric conversion efficiency of about 30%,three times higher than CO2 Laser machine, energy saving and environmental protection.

  • Extremely low cost of use: the power consumption of the whole machine is only 20-30% of the same kind of CO2 laser cutting machine.

  • Extremely low maintenance cost: no laser working gas, optical fiber transmission, no reflection lens, can save a lot of maintenance costs.

  • The product operation and maintenance is convenient: the optical fiber transmission, no need to adjust the light path.

  • Super flexible light guide effect: small size, compact structure, easy to flexible processing    requirements.
