✦ Synopsis

In this paper, we present an experimental and
theoretical study of pulse laser ablation of stainless steel
target. Various parameters, such as laser power, pulse duration,
enthalpy and heat capacity are used. The evaluation of which
software will be suitable for the ablation processes has been
done. The possibility to find micro-craters and microdefects was
noted by using Reflection Optical Microscope (ROM). The ablation
process induced by lasers is a collective phenomenon: that
basically involves two phenomena: the laser radiation-with matter
interaction and the dynamic of the ablation plume. A numerical
solution is derived and stimulated for 2-D laser ablation process.
Only the solid – liquid phase change is considered. This study
contributes to a better understanding of the physical processes
involved in the laser ablation targets.
