CO2 Laser vs Fiber Laser Performance Comparison

Fiber lasers stand out for their efficiency and speed in processing metals, making them ideal for cutting, engraving, marking, and welding applications where metal is the primary material. CO2 lasers, on the other hand, are versatile tools for non-metal materials, offering quality and precision across cutting and engraving applications.

The material types, desired outcomes, and productivity goals, all influence their suitability and efficiency for specific tasks.

CO2 Laser vs Fiber Laser Cutting

Material Type and Thickness Compatibility

  • CO2 Lasers: Excel in cutting non-metal materials such as wood, acrylic, and plastics, able to handle thick materials up to about 1 inch (25 mm), depending on the laser's power. They can also cut metal, but are generally less efficient, especially for thicker or highly reflective metals.

  • Fiber Lasers: Specialize in cutting metal materials, including steel, stainless steel, aluminum, and brass. They can cut metal materials of varying thicknesses efficiently, from thin sheets to those over 1 inch (25 mm), with the exact capability depending on the laser’s power rating.


  • CO2 Lasers: Provide good cutting speeds on non-metals but tend to be slower with metals, particularly as thickness increases.

  • Fiber Lasers: Offer faster cutting speeds on metals, particularly noticeable in thin to medium-thick materials due to their high absorption rate and beam quality.

CO2 Laser vs Fiber Laser Engraving

Material Type

  • CO2 Lasers: Ideal for engraving a wide range of non-metal materials with high precision and quality. They can also engrave coated metals or anodized layers but are not the best choice for direct engraving on bare metals.

  • Fiber Lasers: Best suited for engraving metals and certain types of plastics. They produce high-contrast, permanent markings on metal surfaces.

Speed and Quality

  • Both laser types can achieve high-quality engravings, but the material being engraved will often dictate the choice. Fiber lasers are generally faster at engraving metals than CO2 lasers due to their beam characteristics and interaction with metal surfaces.

CO2 Laser vs Fiber Laser Marking

Material Type

  • CO2 Lasers: Effective for marking on glass, ceramic, wood, and some plastics. The marks are usually surface-level and may not be as durable as those made by fiber lasers on metals.

  • Fiber Lasers: Excel in marking metals and some plastics, producing permanent, high-contrast markings suitable for industrial applications, including traceability and compliance labeling.

Speed and Durability

  • Fiber Lasers: Tend to mark faster and more permanently on metals compared to CO2 lasers, thanks to their beam properties and interaction with materials.

CO2 Laser vs Fiber Laser Welding

Material Type and Thickness Compatibility

  • CO2 Lasers: These can be used for welding a variety of materials, including metals and plastics, but are generally less common for this application due to limitations in beam quality and absorption.

  • Fiber Lasers: Highly effective for precision welding of metals, capable of handling both thin and thick materials. They offer advantages in terms of speed, depth of weld, and minimal heat input.

Speed and Quality

  • Fiber Lasers: Provide superior welding speeds and quality for metals, with high precision and control over the welding process, resulting in strong, clean welds with minimal distortion.

Fiber lasers, with their advanced technology, stand out for their ability to handle a wide range of metal thicknesses and types, including highly reflective metals, which CO2 lasers struggle with.
