A method for laser shock peening an article including laser shock peening
a first area with at least one high fluence laser beam and laser shock
peening a border area between the first area and a non-laser shock peened
area of the article with at least one first low fluence laser beam. The
border area may be laser shock peened with a second low fluence laser
beam or more low fluence laser beams wherein the second low fluence laser
beam and others have a lower fluence than the first low fluence laser
beam. The border area may be laser shock peened with progressively lower
fluence laser beams starting with the one first fluence laser beam
wherein the progressively lower fluence laser beams are in order of
greatest fluence to least fluence in a direction outwardly from the first
area through the border area to the non-laser shock peened area.
