What is a fiber laser?

A fiber laser is a modern device that uses fiber-optic technology for precise metal cutting and engraving. The laser beam is generated in a fiber source and transmitted through optical fibers without mirrors or reflective lenses.

How does a fiber laser work?

The laser works by amplifying light within a fiber medium doped with rare-earth elements (such as ytterbium). Pump diodes generate light that is transmitted into the fiber, where it is amplified and converted into a powerful, focused beam capable of melting or vaporizing metal with extreme precision.

Applications of fiber lasers

Fiber lasers are widely used in industries such as:

• metal cutting – steel, aluminium, copper, brass, titanium;

• engraving and marking;

• machinery and structural parts production;

• automotive and electronics sectors.

Advantages of fiber laser technology

• High precision – smooth, burr-free edges without finishing.

• Energy efficiency – lower power consumption than CO₂ lasers.

• Low maintenance – no mirrors, no calibration needed.

• Long lifespan – up to 100,000 operating hours.
