A short-pulse and high-intensity laser hits the metal surface, and makes the ablative layer on the workpiece surface to absorb the laser energy and generates a rapid-expanding plasma wave. The effects of the plasma shockwave can change the microstructure of the workpiece surface and create a compressive residual stress with depth below the workpiece surface. Thus the metal property in preventing fatigue failure, fighting foreign object damage (FOD) and resisting fretting abrasion can be improved effectively. LSP Features: 1. High Pressure: GPa-TPa, 2. High Energy: GW 3. Ultra High Strain Rate: 106S-1
