Abstract
A method for monitoring the processing of a workpiece includes directing an incident laser beam onto the workpiece and measuring a signal emitted from the workpiece. At least two signals are generated by a detector based upon the emitted signal. A workpiece processing quality is determined based upon the ratio of the two output signals and a magnitude of one of the two outputs.
