Abstract
A technique for ablating a metal workpiece by the use of laser beam radiation at an efficiency higher than heretofore possible and an improved regulation of the ablation process. Undesired side effects of the ablation process are eliminated by the entire and complete ejection of the molten metal at the point of beam impingement so that no material remains on the workpiece in the areas between contiguous points of ablation. The appropriate selection of beam intensity and the selection of pulse shape provide the inventive technique.
