Introduction to Fiber Laser Marking Technology

What is Fiber Laser Marking Technology?

Fiber laser marking technology is a cutting-edge method used to apply permanent markings on various materials. This technology utilizes fiber lasers, which are solid-state lasers that utilize optical fibers as the gain medium. Unlike conventional marking methods, fiber laser marking offers numerous advantages such as high precision, speed, and versatility.

How does Fiber Laser Marking Work?

Fiber laser marking works based on the principle of selective absorption of laser energy by the material being marked. The fiber laser emits a high-intensity laser beam that is focused onto the surface of the material through a lens. The intense laser energy vaporizes or oxidizes the material, creating a permanent mark.
