Abstract

We report on an industrial ultrafast laser system for internal marking and engraving of transparent materials. Current engraving techniques, using nanosecond infrared or UV laser, are either limited to surface marking, or create thermal stress which can lead to fracture of material. Using an infrared ultrafast laser, we describe an industrial equipment able to non-aggressively mark alphanumeric or datamatrices at a high speed, with a high readability. Anti-counterfeiting and normative applications will be presented, as well as integration on a production line.
