Shockwaves in Laser-assisted Manufacturing

 

The shockwave in laser-assisted manufacturing involves intense two-phase processes, and bears an extremely high temperature gradient in space. It could last a relatively short time, yet still has significant impact on the matter ablation process. Our work in this area provides great insight into internal shock wave structure across the plume-ambient gas interface, dual-mass penetration, shockwave-induced spatial confinement, and additive manufacturing.
