Shockwaves in Laser-assisted
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.
