Abstract:
1. A laser material processing system comprising: a laser operable to emit a femtosecond or picosecond laser beam pulse; a shaper operable to shape the pulse; an optic member located in the path of the pulse to broaden the bandwidth of the pulse; a programmable controller connected to the shaper; a detector connected to the controller; and a workpiece micromachined by the pulse, the workpiece including at least one of: silicon or a dielectric material; the controller receiving pulse characteristic signals detected by the detector to optimize laser pulse characteristics for the micromachining of the workpiece; wherein the laser pulse characteristics are optimized based at least in part on the signals which are laser induced breakdown spectroscopy signals; and wherein the detector detects emissions from the workpiece as it is being micromachined.
