What is a fiber laser?
A fiber laser uses an optical fiber doped with rare-earth elements like ytterbium to generate the laser beam. It’s a solid-state laser that delivers high power and efficiency, making it ideal for cutting metals and other tough materials. Fiber lasers are known for their excellent beam quality, fast cutting speeds, and low maintenance.
How fiber lasers work
The laser beam can be delivered to the target directly from the fiber or via a flexible cable, allowing high precision and flexibility in a variety of applications such as cutting, welding, and marking.
Fiber lasers are highly efficient, provide a large cooling surface area, and allow interaction between the pump light and the gain medium. The laser system is compact, energy-efficient, and capable of producing high-quality laser beams.
Applications of Fiber Lasers:
- Metal Cutting: Fiber lasers are particularly effective at cutting metals like stainless steel, aluminum, and brass. Their high power density allows for fast and precise cuts.
- Marking and Engraving: Fiber lasers are also used for engraving and marking metal surfaces due to their high precision and fine beam focus.
- Welding: Fiber lasers are often used in laser welding for automotive and industrial applications.
What is a CO2 laser
A CO2 laser operates by using a gas mixture that includes carbon dioxide, nitrogen, and helium. The laser is produced when electricity excites the gas mixture, producing an infrared laser beam. CO2 lasers are highly effective for cutting and engraving non-metal materials, such as wood, plastics, acrylics, and glass.
Applications of CO2 Lasers:
- Non-metal Cutting and Engraving: CO2 lasers are best known for their ability to cut and engrave materials like wood, paper, acrylics, and textiles.
- Signage and Art: CO2 lasers are widely used in signage production and artistic applications due to their precision in engraving and etching non-metal materials.
- Medical Applications: CO2 lasers are also used in the medical field for surgeries and other delicate procedures.

Co2 vs fiber laser wave length
- CO2 Laser: Operates at a longer wavelength, typically around 10.6 micrometers (µm).
- Fiber Laser: Operates at a much shorter wavelength, typically around 1.06 micrometers (µm).
This significant difference in wavelength directly impacts the types of materials each laser can effectively cut and process.
Fiber laser cut quality vs co2 laser
- Thinner materials: Fiber lasers excel at cutting thin materials with exceptional precision, producing clean edges with minimal dross and burrs.
- Thicker materials: While both can cut thicker materials, CO2 lasers often have a slight edge in terms of edge quality, providing smoother finishes.
- Tipo di materiale: The type of material also influences cut quality. Fiber lasers are particularly effective on reflective metals, while CO2 lasers tend to perform better on non-metals.
Factors Affecting Cut Quality:
- Potenza del laser: Higher power typically leads to better cut quality.
- Nozzle type: The correct nozzle is crucial for optimal cut quality.
- Assist gas: The type and flow rate of assist gas can significantly impact results.
Fiber laser vs co2 laser speed
Thin materials: Fiber lasers cut thin materials much faster than CO2 lasers.
Thick materials: The difference in cutting speed between the two laser types becomes less pronounced for thicker materials, with CO2 lasers sometimes offering comparable speeds.
Factors Affecting Cutting Speed:
- Nozzle type and gas flow: The correct nozzle and gas settings optimize cutting speed.
- Spessore materiale: Thinner materials are cut faster with both types of lasers, but the advantage is more pronounced for fiber lasers.
- Tipo di materiale: The type of material being cut influences cutting speed. For instance, fiber lasers excel at cutting conductive materials like metals.
