Fiber Lasers at a Glance

Industrie & Beschriftung

Fiber (galvo) lasers are the first choice for marking and engraving metals with high speed and precision. They are compact, fast, and perfect for serial marking of tools, tags, jewelry and parts.

Fast metal marking

High speed on steel, aluminum, brass and more – crisp codes and logos.

Compact & productive

Small footprint with big throughput; ideal for workshops and small businesses.

Sources & power

Common sources: 20–50 W; MOPA adds control over pulse width for color on steel and fine plastics work.

  • 20 W – entry for metal marking
  • 30–50 W – faster throughput and deeper engraving
  • MOPA – color marking on steel, plastics tuning

Pros & limits

  • Pros
  • Very fast on metals
  • High precision with galvo steering
  • Compact footprint
  • Limitations
  • Not suitable for large-area cutting of wood/acrylic
  • Learning curve for marking parameters
  • Eye safety requires proper enclosure

Material overview

Suitable materials

  • Stainless steel
  • Aluminum
  • Brass / copper (etch/mark)
  • Plastics (additives)

Better avoid

  • Wood / leather

Fiber laser FAQ

What can fiber lasers do?
💡
Engrave and mark metals at high speed with excellent contrast; some plastics with additives; color marking on steel with MOPA.
How do I choose power?
💡
20 W is great for marking; 30–50 W for deeper, faster work. Consider MOPA if you need color on steel or fine plastcs control.
Safety considerations?
💡
Enclose the beam path and use proper eyewear; prefer certified enclosures for Class 1 operation.
