摘要： 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/cm2, with spot size greater than 4 mm are used, including a pulse with on the order of 16 ns, with spot size greater than 9 mm2. 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.

摘要： A beam delivery technology for high power laser systems, like laser peening systems, for work pieces which may have compound curvatures, includes placing an optical assembly having a receiving optic, beam formatting optics and a scanner mounted thereon, in a position to receive laser pulses from a laser source and within an operating range of the process area. Polarized laser pulses are delivered to the receiving optic while the position of the optical assembly remains unchanged. The pulses proceed through the beam formatting optics to the scanner, and are direct to respective impact areas having nominal shapes and locations on the work piece. The scanning process includes for each laser pulse, setting direction, divergence, polarization, rotation and aspect ratio of the laser pulses output from the scanner, to control the polarization, shape and location on respective impact areas.
