Abstract
This paper presents the construction of a computer model of crater formation during nanosecond laser evaporation of matter by the example of monocrystalline silicon. The computer simulation is used to determine the dynamics of crater formation on the material surface when exposed to nanosecond laser pulses. The diameter of the obtained crater and its depth were evaluated. The corresponding experiments on laser ablation of monocrystalline silicon were also carried out. The analysis of experimental data and simulation results showed that depending on the pulse duration and energy density of laser radiation the mechanism of material removal changes. Thus, the presence of the liquid phase in the ablation process seriously affects the depth and diameter of the crater for the entire range of energy densities from 0.4 to 104.0 J/cm2 . It is shown that a computer model can determine the volume of removed material due to evaporation and evaluate the effect of the liquid phase on crater characteristics.
