What is a fiber laser marking machine?

A fiber laser marking machine utilizes a fiber optic system to generate and deliver high-intensity laser beams for marking or engraving various materials. Renowned for their efficiency, precision, and versatility, fiber lasers excel in marking metals, plastics, and other industrial surfaces with exceptional durability and clarity.

Fiber Laser Marking Technology: How It Works

Fiber laser marking technology is an advanced solution that utilizes a high-intensity laser beam transmitted through a fiber optic system to create permanent, precise markings on various materials. Unlike traditional laser systems, fiber lasers use a fiber-based gain medium, ensuring greater efficiency, durability, and minimal maintenance. This technology allows for high-speed, contactless engraving with exceptional accuracy, making it ideal for industries requiring detailed and durable markings.

Fiber vs. Traditional Laser Marking: Key Differences

When comparing fiber laser marking with traditional laser systems, the advantages become clear. Standard lasers, such as CO₂ lasers, excel at marking non-metallic surfaces but lack the precision and durability of fiber lasers for metals and high-resistance materials. Fiber lasers generate finer, more detailed engravings with greater depth control, ensuring superior readability and longevity. Below is a visual comparison demonstrating the difference in marking quality between fiber laser and conventional laser technologies.

Beam Quality: Fiber vs. CO₂ Lasers

Beam quality plays a crucial role in determining the energy concentration and marking precision of a laser system. It is measured by the M² value, where a value closer to 1 indicates a higher-quality, more focused beam. Fiber lasers typically have an M² value around 2, producing a highly concentrated and stable beam ideal for precise, high-contrast markings on metals and industrial materials. 

In contrast, CO₂ lasers generally exhibit a higher M² value, resulting in a broader, less focused beam. While CO₂ lasers are excellent for marking organic and non-metallic materials, their beam quality does not match the fine detail and depth control that fiber lasers achieve on metals and other high-durability surfaces.
