Abstract
A method of directing a laser beam along a desired path on a workpiece and at spaced intervals delivering a pulse of laser energy comprising the steps of: using a position command stream and position feedback to control the positioning of galvanometer scanned mirror or mirrors to define the path a laser beam will travel to intersect the desired path on the workpiece; and using position feedback alone to determine when a pulse of laser energy is delivered to strike the workpiece at locations such that are uniformly overlapped along the path notwithstanding variations in galvanometer mirror velocity.
