摘要： A laser shock peening apparatus includes a laser unit for generating at least one laser beam aimed at a laser shock peening area and an anti-feedback means for preventing electromagnetic radiation reflections from the target area from entering the laser unit during laser shock peening and the anti-feedback means is located between the laser unit and a final focusing lens. The anti-feedback means may include an optical isolator at an output of the laser unit such as a faraday isolator. Alternative optical isolators may include thin film polarizers, glan prism polarizers, independent pig tailed optical isolators, mirrors with enhanced P or S polarization coatings. The laser unit may include an oscillator and a final amplifier and the output of the laser unit located after the final amplifier.

摘要： A continuous motion laser shock peening apparatus and method for laser shock peening a workpiece. A laser controller modulates and fires a laser beam from a laser unit. A motion controller is controllably connected to a manipulator and to the laser controller to fire the laser beam based on axis position feedback from a speed control of the motion controller. The laser controller has a standby mode for flashing a laser flash lamp at a flash rate without triggering the laser beam and a firing mode that triggers and fires the laser beam in laser beam pulses. The laser controller includes a synchronizing means for synchronizing a triggering signal provided to the laser interface controller by the computerized motion controller to fire the laser beam pulses and the flash rate substantially at a time when the laser beam pulses are to be generated.
