Laser Shock Processing (LSP) is a technique for strengthening of metals, by inducing a compressive residual stress [1,2]. In this work, we present a review of experimental results obtained by our research group on the laser shock processing of Al 6061-T6, during the last 15 years. A convergent lens is used to deliver a high energy laser pulse, produced by a Q-switched Nd:YAG laser, on the surface of aluminum 6061-T6 specimens. Fatigue crack growth and fracture [1], high level compressive residual stresses [2], characterization of the shock wave [3], the effect of pulse density on the residual stress distribution, and other experimental results are presented [4].
