　　In this paper, the high energy laser pulse was used to treat 7050-T7451 aluminum alloys treated with laser spot with 6mm diameter.The principle of LSP was presented and the compressive residual stress was measured by XRD, fatigue life of fatigue comparison test was given after LSP on 7050-T7451 aluminum alloys.The results showed the performance of 7050-T7451 aluminum alloys were improved after LSP with high energy pulse laser.
