  • System and method for controlling laser shock peening
    Patent number: 7816622
    Abstract: A laser shock peening system including a workpiece is provided. The laser shock peening system includes a workholding fixture configured to hold the workpiece. The laser shock peening system also includes a laser source configured to emit multiple laser beam pulses on the workpiece. The laser shock peening system further includes an absorptive layer disposed on the workpiece, the absorptive layer configured to absorb the laser beam pulses from the laser source into the workpiece. The laser shock peening system also includes a transparent constraining layer disposed between the laser source and the absorptive layer. The transparent constraining layer is also configured to provide a pressure medium configured to direct multiple reflected laser generated shock waves from the workpiece back into the workpiece. The laser shock peening system also includes a transducer disposed on the workholding fixture and configured to detect multiple acoustic signals emitted from the workpiece.
