A UID data matrix with 3mil data cell size was laser marked on polished stainless steel stock. The mark produced had excellent contrast. The total mark time was 0.5 seconds. A 20 Watt CW Fiber laser was used to mark the dimensional data matrix; a single spot of 50 microseconds. The resulting mark took 0.5 seconds.
