In the industrial market, co2 laser and fiber laser are the most commonly used fiber laser sources, but they are more commonly used in metal cutting, engraving and marking, and there are still many differences.
This article mainly focuses on láser de fibra vs co2. I hope it will help you choose the appropriate fiber laser.
What is a fiber laser?
Fiber lasers are optical fibers whose active gain medium is doped with rare earth elements such as erbium, yttrium, neodymium, antimony, neodymium, thorium, and holmium. These elements provide the necessary light amplification without the need for external reflectors.
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.
What is a CO2 laser
A gas-filled tube surrounding it serves as the laser medium. The gas mixture usually contains carbon dioxide (CO2) and other gases such as nitrogen (N2), helium (He), and sometimes hydrogen (H2) or xenon (Xe).
Fiber laser vs co2
| Factor | Láser de fibra | Láser de CO2 |
|---|---|---|
| Aplicaciones | Metals, some non-metals, cutting, marking, welding | Non-metals, some metals, cutting, engraving, marking |
| Compatibilidad de materiales | Highly effective on metals, limited on non-metals | Highly effective on non-metals, less effective on metals |
| Cutting Speed and Precision | High speed and high precision | Moderate speed, high precision |
| Calidad del haz | High (very focused beam, minimal divergence) | Good (larger spot size than fiber lasers) |
| Power Consumption and Efficiency | Lower power consumption, higher efficiency | Higher power consumption, lower efficiency |
| Maintenance Requirements | Lower (solid-state, fewer moving parts) | Higher (gas refills, alignment checks) |
| Cost (Initial and Operational) | Higher initial cost, lower operational cost | Lower initial cost, higher operational cost |
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.
- Material type: 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:
- Potencia del láser: 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.
- Material thickness: Thinner materials are cut faster with both types of lasers, but the advantage is more pronounced for fiber lasers.
- Material type: The type of material being cut influences cutting speed. For instance, fiber lasers excel at cutting conductive materials like metals.
- Potencia del láser: Higher laser power typically results in faster cutting speeds.
