A laser marking system comprises at least one controller to control an array of optical devices, between a laser source and a scan head. The array applies a selected pattern of portions of the received spatial profile of the laser beam to the substrate to achieve a second intensity different from the first intensity of laser beam at a rate of power deposition relative to a rate of thermal diffusion in the substrate for a predetermined time interval to thermally heat locations of the substrate with the selected pattern of the portions. The second intensity effectuates carbonization of materials of the substrate to create a mark without ablation.
