LASER PEENING APPARATUS AND METHOD FOR USING ARBITRARY LASER PULSE

摘要

PURPOSE: Laser peening device and method using a laser pulse of any waveform are provided to minimize the damage to a target by applying a laser pulse of any waveform to the target depending on the physical characteristic of the target. CONSTITUTION: A laser peening device using a laser pulse of any waveform comprises a characteristic determining unit(213), a pulse generating unit(215), and an irradiating unit(217). The determining unit determines the physical characteristic of a target(201). The pulse generating unit generates a laser pulse of any waveform according to the determination result. The irradiating unit irradiates the generated laser pulse to the target.
