UID marking a two-dimensional data matrix with 3mil data cell size was marked on polished plate stainless steel stock. The mark produced had excellent contrast. Total marking time was 0.6 seconds. A 20 Watt CW laser was used as opposed to Q-switched Fiber Laser to allow for the Contrast ratio to be as high as possible.
