Technical Comparison: Fiber Laser vs. CO2 Laser for Metal

When it comes to metal marking, fiber lasers have distinct advantages over CO2 lasers:

Feature	Fiber Laser	CO2 Laser
Metal Absorption	Excellent (1064nm wavelength)	Poor (10,600nm wavelength)
Precision	0.01mm minimum line width	0.1mm minimum line width
Speed	3-5x faster than CO2	Slower
Maintenance	Air-cooled, low maintenance	Water-cooled, higher maintenance
Lifespan	100,000+ hours	20,000-30,000 hours
Energy Efficiency	30-40% efficiency	10-15% efficiency

Fiber lasers excel at metal marking because their 1064nm wavelength is highly absorbed by metallic surfaces, allowing for precise, high-contrast markings without the need for surface coatings. CO2 lasers, while versatile for non-metals, typically require marking sprays or pastes to create visible marks on metal.

MOPA Fiber Laser Technology: The Game Changer

MOPA (Master Oscillator Power Amplifier) fiber lasers represent the pinnacle of laser marking technology. Unlike traditional Q-switched fiber lasers, MOPA systems allow independent control of pulse frequency (1-4000 kHz) and pulse width (2-500 ns). This flexibility enables several advanced capabilities:

Color Marking: By precisely controlling pulse parameters, MOPA lasers can create black, white, green, and red marks on stainless steel and titanium through controlled oxidation effects.

Fine Detail Work: The adjustable pulse width allows for finer line widths (down to 0.01mm) and smoother edges, making MOPA lasers ideal for intricate designs and small text.

Material Versatility: MOPA technology can process a wider range of materials, including anodized aluminum, thin metal sheets, and sensitive electronic components without causing deformation.

High-Speed Processing: With engraving speeds up to 15,000 mm/s, MOPA lasers significantly outperform traditional marking methods.
