Abstract:
Laser ablation is a versatile and widespread technique, applied in an
increasing number of medical, industrial and analytical applications.
A hydrodynamic multiphase model describing nanosecond-laser ablation
(ns-LA) is outlined. The model accounts for target heating and mass
removal mechanisms as well as plume expansion and plasma formation.
A copper target is placed in an ambient environment consisting of helium
and irradiated by a nanosecond-laser pulse. The effect of variable laser
settings on the ablation process is explored in 1-D numerical simulations.
