Difference between fiber and CO2 lasers
When choosing a laser machine, it's essential to select the right type of laser that fits your specific applications. Two popular types are fiber lasers and CO2 lasers. While both technologies involve laser technology, there are significant differences in their operation, applications, and advantages. In this article, we will explain these differences in detail.
What is a fiber laser?
A fiber laser uses fiber optics to generate laser light. These lasers are often compact and efficient, utilizing a diode laser as a source to send light into an optical fiber. The fiber guides the light and amplifies it, resulting in a powerful laser beam.
Advantages of Fiber Lasers:
- Efficiency: Fiber lasers are highly energy-efficient, leading to lower operational costs.
- High Speed: They can cut quickly and accurately, making them ideal for production environments.
- Low Maintenance: With fewer moving parts, fiber lasers require less maintenance.
- Material Versatility: They excel at cutting metals such as stainless steel, aluminum, and copper.
What is a CO2 laser?
A CO2 laser uses a gas mixture (primarily carbon dioxide) to generate laser light. These lasers are typically larger and more complex than fiber lasers and use an electrical discharge to excite the gas, producing a powerful laser beam.
Advantages of CO2 Lasers:
- Material Diversity: CO2 lasers are highly effective for cutting and engraving non-metal materials like wood, plastic, and leather.
- Deep Cutting: They can make deep cuts in thicker materials, making them ideal for specific applications in woodworking and other industries.
- Gentle Beams: The longer wavelength of CO2 lasers makes them less suitable for metals but extremely effective for many other materials.

When to choose which laser?
- Opt for a fiber laser if your main application involves cutting and engraving metal materials. They are faster, more efficient, and offer lower operational costs over time.
- Opt for a CO2 laser if you primarily work with non-metal materials or require deeper cuts in wood or plastic. They provide excellent performance for a wide range of materials beyond metal.
