Whats the difference between co2 laser cutting machine and fiber laser cutting machine?

CO2 laser cutting machines and fiber laser cutting machines are both used for cutting various materials, but they differ in terms of their laser sources, efficiency, capabilities, and applications. Here's a breakdown of the key differences:

Laser Source:

CO2 Laser: CO2 lasers use a gas mixture (carbon dioxide, nitrogen, and helium) as the laser medium to produce the laser beam. These lasers emit infrared light with a wavelength of around 10.6 micrometers.

Fiber Laser: Fiber lasers use a solid-state laser source, where the laser medium is a fiber optic cable doped with rare-earth elements like erbium, ytterbium, or thulium. Fiber lasers emit light with a wavelength typically between 1 and 1.1 micrometers.


CO2 Laser: CO2 lasers have a longer wavelength, which makes them well-suited for cutting non-metallic materials like wood, acrylic, plastics, fabrics, and some metals with reflective coatings.

Fiber Laser: Fiber lasers have a shorter wavelength, which is more efficiently absorbed by metals. This makes them excellent for cutting various metals, including stainless steel, aluminum, brass, and copper.

Efficiency and Power:

CO2 Laser: CO2 lasers are known for their versatility but are generally less efficient when it comes to cutting metals. They are often used for intricate and detailed cuts on non-metallic materials.

Fiber Laser: Fiber lasers are highly efficient at metal cutting due to their shorter wavelength and higher power density. They can cut through thick metals with greater speed and accuracy.

Cutting Speed:

CO2 Laser: CO2 lasers might be slower when cutting metals compared to fiber lasers.

Fiber Laser: Fiber lasers are faster when cutting metals due to their higher energy concentration and better absorption by metal surfaces.


CO2 Laser: CO2 lasers have more complex gas systems that require regular maintenance and gas refilling.

Fiber Laser: Fiber lasers have a simpler solid-state design, resulting in less maintenance and longer lifespans.

Precision and and efficiency required for your specific applications.
