A method for manufacturing applied to workpieces, such as large flat-panel liquid crystal displays (LCDs) and the like, including identifying and classifying targets on the workpiece, mounting workpiece on a stage, and controlling a laser to generate pulse of light on a single beam line that are adapted to the classification of the target. The laser includes a short pulse mode and a long pulse mode, and provides selectable wavelengths, which are adapted to particular operations on the target. The pulses of light are delivered in both of the first and second modes on the single beam line through an optical system to the targets on the workpiece.
