Laser technologies
Choose the wavelength for the material.
Fiber, MOPA, CO2, and UV lasers interact differently with metals, plastics, coatings, glass, and organic materials. The right source depends on the required result.
MOPA fiber
More control over pulse width and frequency for contrast, fine heat control, and color effects.
Anodized aluminumPlasticsColor marking
CO2 laser
Strong absorption on many organic, coated, and non-metal materials.

UV laser
Fine marking with limited heat input for sensitive substrates and precision features.

At-a-glance comparison
Start with the mark—not wattage.
| Technology | Typical strengths | Common materials | Questions to verify |
|---|---|---|---|
| Fiber | Speed, durability, metal contrast, engraving | Steel, aluminum, copper alloys, some plastics | Depth, contrast, surface finish, cycle time |
| MOPA | Pulse control, fine contrast, lower heat options | Anodized aluminum, stainless steel, selected plastics | Color target, heat sensitivity, repeatability |
| CO2 | Cutting/engraving organic materials and marking coatings | Wood, acrylic, paper, leather, glass coatings | Thickness, edge quality, smoke extraction |
| UV | Small features and low-heat marking | Glass, electronic parts, polymers, packaging films | Contrast, damage threshold, field size |
These are practical starting points, not universal guarantees. Material formulation, additives, coatings, surface finish, and the required mark can change the result. Sample testing is recommended when appearance or process window is critical.
