Numerical simulation of the dynamics of phase transitions in CdTe induced by irradiation with nanosecond pulses of an excimer laser

Simulation of the effect of KrF nanosecond pulse excimer laser radiation (λ = 248 nm, τ = 20 ns) on phase transitions in cadmium telluride was performed taking into account the diffusion of the melt components and their evaporation from the surface. It is shown that the surface region of the melt is enriched with tellurium due to the evaporation and diffusion of the cadmium telluride components. The obtained value 0.05 J/cm 2 of the threshold energy density for melting is in reasonable agreement with the experimental data.
