Peening Lasers

Peening Lasers

Peening is a process in which a compressive force is applied to the surface of a part after machining with the goal of slightly deforming the surface to smooth out any residual micro-cracks.  Traditionally this is done by firing small metal or glass beads at the surface of the part at high velocity causing small deformations that over time smooth out the surface.  This same process can be performed using lasers, in which the part is coated in an absorbing black material (such as black paint), and a q-switched laser is scanned across the surface.  In the case of peening lasers, pulses are focused onto the surface and absorbed by the coating, ablating it, and a compressive shock wave is sent through the material deforming the surface under the spot.  On this page, you will find a list of all of the peening lasers we offer including flashlamp pumped q-switched laser systems with up to 300J per pulse.
