METHOD AND APPARATUS FOR FINE-SCALE TEMPORAL CONTROL FOR LASER BEAM MATERIAL PROCESSING

The present application relates to a method and an apparatus. The method includes directing a laser beam (404) to a target (410) along a scan path at a variable scan velocity and adjusting a digital modulation during movement of the laser beam (404) along the scan path and in relation to the variabl...
