Fiber Laser vs CO2 Laser: Understanding the Key Differences

Are you in the market for a laser cutting or engraving machine but not sure which type of laser is best suited for your needs? The main difference between Fiber Laser and CO2 Laser technology is in the wavelength of the laser beam. Fiber Lasers use a solid-state laser source and generate high-powered laser beams with a wavelength ranging between 1070nm - 1080nm, while CO2 Lasers use a gas laser source and generate laser beams with a wavelength of 10600nm.

Fiber Lasers are more energy efficient, have faster processing speeds, require less maintenance, and can mark or engrave a wider range of materials than CO2 Lasers, such as metals, plastics, glass, and ceramics. CO2 Lasers, on the other hand, work better on organic materials such as wood, leather, and fabrics.

At Lin Laser Technology Co., Ltd. in China, we specialize in the manufacturing and supply of both Fiber and CO2 Laser cutting and engraving machines. We are committed to providing our customers with high-quality products and excellent service. Contact us to learn more about our machines and which type of laser technology is best for your specific needs.
  • When it comes to industrial laser cutting, there are two main types of lasers: fiber lasers and CO2 lasers. The basic difference between these two types of lasers lies in their wavelength and the medium they use to generate the laser beam. Fiber lasers use a fiber optic cable to generate and focus the laser beam. The laser is created by passing a high-intensity laser beam through a fiber optic cable that is coated with rare-earth elements such as erbium, ytterbium or neodymium. The laser beam is then focused and directed onto the material to be cut. CO2 lasers, on the other hand, use a carbon dioxide gas mixture as the medium to generate and focus the laser beam. When a high voltage is applied to the gas mixture, the molecules become excited and emit photons, generating a laser beam. There are several differences between fiber lasers and CO2 lasers that affect their performance and suitability for different applications. Fiber lasers offer superior beam quality and cutting speed, making them ideal for the cutting of thin and reflective materials. CO2 lasers, on the other hand, are better suited for thick and non-reflective materials, such as wood, plastics and acrylics. In summary, the choice between fiber lasers and CO2 lasers is usually determined by the materials being cut, the thickness of the material, and the desired speed and quality of the cut. By understanding the differences between these two laser cutting technologies, you can select the one that is best suited to your specific needs.
