What Is Fiber Laser Marking? (2026 Updated Technical Guide)
Fiber laser marking is one of the most widely used industrial marking technologies for making permanent, high-contrast, and precise markings on metal and certain plastic surfaces. Fiber laser systems operating at a wavelength of 1064 nm provide high performance in applications such as serial number marking, DataMatrix, QR code, and logo marking. Thanks to the non-contact working principle, surface deformation is minimal and long-lasting marking is achieved. This guide explains in detail the working principle, advantages, and areas of use of fiber laser technology.
How Does Fiber Laser Marking Technology Work?
What is a fiber laser?
Fiber laser is a laser technology in which the laser beam is generated and transmitted within fiber optic cables.
Wavelength
Fiber laser systems operate at a wavelength of approximately 1064 nm.
Non-contact working principle
The laser beam marks the surface without physical contact.
Energy density
Thanks to its high energy density, it delivers effective results on metal surfaces.
Marking method
Marking is performed by surface oxidation, annealing, or engraving methods.
Contrast formation
Contrast is achieved by creating a color change on the surface with the laser.
Marking precision
Fiber laser systems offer high resolution.
Speed performance
It can perform marking at high speed.
Consumable requirement
Fiber laser systems do not require consumables.
Industrial application areas
- Automotive parts
