Laser marking has been a well accepted process in the medical industry for many years. These stainless steel parts were marked using Nd:YAG lasers in CW mode. This creates a dark mark onto the polished surface. No material is removed during the process leaving the surface smooth, a necessity in surgical procedure so that the instrument does not have potential contamination areas. Today, this process would be better suited to Fibre technology which processes at a much higher pulse rate.
This customer had very strong environmental constraints when purchasing equipment, and required air cooled equipment rather than the more traditional water cooled units. Their investment was configured around lower powered air cooled equipment.
