Abstract
A predictive pulse triggering (PPT) method enables precise triggering of a laser beam in a link-processing system. The PPT method entails triggering the laser beam based on estimated relative motion parameters of the target and laser beam axis. The PPT method allows for a six-fold improvement in laser positioning accuracy over the conventional, entirely measurement-based method.
