Micro-sculpting for generation holographic security markings on metal parts

Krystian Wlodarczyk, Stefanie Giet, Marcus Ardron (Renishaw), Nick Weston (Renishaw), Duncan Hand

Overview

Phase holographic structures were successfully generated on the surface of stainless steel using a novel laser marking process based on the laser micro-sculpting approach, known as ‘YAGboss’. This research was carried out in collaboration with Renishaw plc (Edinburgh)..
