Abstract
A method for laser shock peening an article by simultaneously firing low energy first and second laser beams to form pairs of longitudinally spaced apart first and second laser shock peened spots that are on opposite sides of the article, simultaneously laser shock peened, and transversely offset from each other. Each of the low energy first and second laser beams having a level of energy of between 1-10 joules.
