What Is Fiber Laser Technology? Industrial Fiber Laser Marking Guide
Fiber laser technology is one of the most widely used laser systems in modern industrial manufacturing. It enables high-contrast, permanent, and fast marking, especially on metal surfaces. Fiber laser marking machines create microscopic changes on the material surface with a high-intensity laser beam operating at a wavelength of 1064 nm. This technology is widely used for serial numbers, DataMatrix, QR codes, logos, and technical labeling applications.
Basic Operating Principle of Fiber Laser Technology
What is a fiber laser?
A fiber laser is a laser technology in which the laser beam is generated and amplified within optical fiber cables. In this system, the laser beam is multiplied and strengthened inside fiber optic cables containing special dopants.
How does a fiber laser work?
In fiber laser systems, diode lasers are used as the energy source. This energy is transferred to the fiber optic cable, and the laser beam is generated within the optical resonator.
What does the 1064 nm wavelength mean?
The most common wavelength of fiber lasers is 1064 nanometers. This wavelength is absorbed at a high rate, especially by metal surfaces.
How is the fiber laser beam directed?
The laser beam is directed through galvo mirrors. These mirrors enable the laser beam to move rapidly across the surface.
Fiber laser marking process
When the laser beam is focused on the surface, a heat or oxidation reaction occurs on the material surface. This reaction creates the marking contrast.
