Marking

Laser marking is the process by which a beam is used to produce permanent, high-contrast markings on a wide range of materials, including metals, plastics, and ceramics. It is being increasingly deployed throughout various industries to ensure the traceability of products and parts.

An introduction to laser marking

As its name implies, laser marking involves the use of a focused continuous-wave, pulsed, or ultrashort-pulsed beam of light that interacts with the surface of a material to alter its appearance and properties.
