Large Field Marking With Steered Beam Fiber Laser Marking Systems

By Jim Earman, Jimani Inc.

Very large marking fields are not practical with steered beam fiber laser marking systems. Marking fields larger than about 12 inches square produce focused spot sizes that are too large to provide sufficient power density for engraving applications, and linewidths too broad for detailed marking applications.In order to achieve large marking fields with steered beam fiber laser marking systems, the information to be marked must be sectioned into “tiles” that are no larger than the marking field. This article discusses the use of galvo drive systems in large field marking and how it is done with good quality hardware and software.
