Abstract

In laser-materials processing, the maximization of workpiece quality depends in part on optimizing conditions of laser beam size and fluence. Taking as an example the case of misfocus in sharp threshold laser ablation, the author describes the quality variations in laser-material processing that can be caused by a moving workpiece that jitters in and out of the laser beam's focal plane. He also discusses the possibility of engineering specific materials for improved misfocus tolerance.
