    Abstract: A method of manufacturing a driver, or other types of golf club, includes inducing residual compressive stress by high intensity laser shock peening to form an array of laser shock peened impact zones on the club face. Laser pulses having fluence greater than 4 GW/cm 2 , with spot size greater than 4 mm 2 are used, including a pulse with on the order of 16 ns, with spot size greater than 9 mm 2 . Residual compressive stress of more than 400 MPa penetrating with a depth of more than 0.2 mm are imparted, without increased hardening in or damage to the face of the club. Laser shock peening a pattern that covers an interior area leaves the perimeter unpeened, inducing a stress gradient between interior area and the perimeter of the club face. Multiple layers of arrays of laser shock impact zones are applied on the club. The technology is readily applied to assembled club heads.

    Abstract: A method for laser shock processing a device, including a metallic body having a surface, comprises conformally applying a compliant solid material to the first region on the surface of the metallic body and applying a layer of ablative material to the second region on the surface of the metallic body. A damping liquid is flowed over the layer of ablative material. An array of pulses of laser energy is directed through the damping fluid to impact the layer of ablative material on the surface and peen the surface in the second region. The pulses induce pressure waves within the metallic body which propagate to the surface in the first region. The compliant solid material acts as a momentum trap, so that the acoustic waves are at least partially coupled into the compliant solid material and attenuated outside of the metallic body.

    Abstract: A hybrid ablation layer (10, 14) that comprises a separate underlayer (10) is applied to a material (12) to prevent pitting resulting from laser peening. The underlayer (10) adheres to the surface of the workpiece (12) to be peened and does not have bubbles and voids that exceed an acceptable size. One or more overlayers (14) are placed over and in contact with the underlayer (12). Any bubbles formed under the over layers (14) are insulated from the surface to be peened. The process significantly reduces the incidence of pits on peened surfaces.
