Fiber Laser Cutting of Metals: A Comprehensive Review
This in-depth review explores the significant advantages of fiber lasers in metal cutting applications, emphasizing their remarkable efficiency, speed, and versatility across various materials. It also thoroughly examines the critical influence of wavelength and beam quality on overall cutting performance.Jones, A., et al., Optics & Laser Technology (2020)
Key Differences in CO₂ Laser Cutting Machine Specifications
CO₂ lasers utilize a gas mixture (CO₂, N₂, He) and operate at a longer wavelength of 10.6 µm. Their typical specifications are:
Key Differences
One of the most notable differences is wavelength. Fiber lasers operate at a much shorter wavelength of 1,070 nm, while CO₂ lasers use a longer wavelength of 10.6 µm. This difference in wavelength is a key factor in determining which materials each laser can effectively process.
Another distinction is their power range. Fiber lasers are known for their high power, with a range of 1 kW to 40 kW, making them suitable for heavy-duty cutting and welding. In contrast, CO₂ lasers have a more moderate power range of 500 W to 8 kW, which is ideal for a wider variety of applications, including engraving and cutting.
Performance and Efficiency
Beam quality is where fiber lasers truly excel. Their beam quality, measured by the M² value, is less than 1.2, indicating a near-perfect, highly focused beam. CO₂ lasers have a lower beam quality with an M² of 1.5–2.0, meaning the beam is less focused. This superior beam quality allows fiber lasers to achieve higher precision and cut through reflective metals more effectively.
Fiber lasers also boast a higher efficiency of around 30%, converting more electrical energy into usable laser power. CO₂ lasers are less efficient, converting only about 10–15% of their energy into light.
Ideal Applications
The differences in wavelength, power, and efficiency make each laser type suited for specific materials. Fiber lasers are the ideal choice for cutting and marking highly reflective metals such as stainless steel and aluminum. Due to their shorter wavelength, they are absorbed more readily by these materials. Conversely, CO₂ lasers are the preferred tool for a wide range of materials, including wood, acrylic, and thick carbon steel, as their longer wavelength is better absorbed by these non-metallic substances.
CO₂ machines demonstrate exceptional performance in cutting non-metallic materials and thicker grades of steel, although they generally require more extensive maintenance and a larger operational footprint compared to their fiber counterparts.

Understanding the Relationship Between Laser Power and Cutting Speed
Increased laser wattage enhances photon density within the cutting zone, accelerating the melting and vaporization processes. As laser power is doubled, cutting speed can often increase by 20–30% on the same material thickness, directly boosting parts throughput and significantly reducing overall cycle time.
Optimizing Laser Power for Varied Material Thicknesses
- Match Power to Thickness: Employ lower wattage settings (1–2 kW) for sheet thicknesses ranging from 1–4 mm to achieve the highest edge quality.
- Increase Power for Thicker Materials: Transition to higher power levels (6–10 kW) when cutting steel plates from 10–20 mm to maintain efficient cutting speeds.
- Fine-Tune Assist Gas Pressure: Adjust the pressure of nitrogen or oxygen assist gas to complement the laser power, ensuring clean and precise cuts.
Precisely optimizing power settings for each specific thickness range is crucial for preserving cut quality and minimizing material waste.
Typical Power Ranges for Fiber and CO₂ Lasers
- Fiber Lasers: Commonly available from 1 kW up to 40 kW, with 1 kW increments being standard.
- CO₂ Lasers: Typically range from 500 W to 8 kW, often in 250 W or 500 W increments.
Many fabrication shops opt to standardize on a mid-range fiber laser unit (e.g., 4 kW–6 kW) for general steel fabrication needs, supplementing their capabilities with higher-power machines for contracts involving heavy plate processing.
How Power Output Impacts Production Efficiency and Uptime
Consistent and appropriately matched power output minimizes thermal stress on both the workpiece and the machine's optics, thereby extending component lifespan and enhancing schedule reliability. Efficient power-to-speed ratios lead to fewer material handling issues, reduced operator intervention, and higher machine utilization rates, particularly within automated cell configurations offered by Machine Tool Specialties.
Critical Accuracy and Precision Specifications You Need to Know
For quality-driven fabrication shops, achieving tight tolerances and consistent, repeatable performance is non-negotiable, making accuracy and precision metrics essential.
Defining Accuracy in Laser Cutting Machines
Accuracy refers to how closely the actual cut path aligns with the programmed coordinates. Typical machine accuracy specifications range from ±0.05 mm to ±0.1 mm across the entire work area, ensuring that parts meet their dimensional requirements from the very first cut.
The Meaning of Precision for Repeatability in Laser Cutting
Precision, often referred to as repeatability, measures a machine's capability to return to the exact same coordinate point under identical operating conditions. High-precision laser systems boast repeatability ps as tight as ±0.02 mm, which is absolutely critical for nested cutting operations and batch production where perfect part alignment is paramount.
