| Abstract: | Many features involved in the problem of heat flow through a semifinite metal sample irradiated with nanosecond laser pulses are discussed with reference both to the underlying physics and to the numerical solution of the heat diffusion equation. Analytical expressions for several quantities, such as average velocities for the liquid-solid interface motion, maximum melted depth, and maximum surface temperature are presented. Experimental impurity profiles detected in Al samples after laser irradiation are analyzed on the basis of a diffusion-segregation hypothesis. The effects of ruby laser irradiation on virgin and ion-implanted Al single crystals, studied by using Rutherford backscattering and channelling are discussed in terms of epitaxial lattice regrowth, defect formation and metastable solid solutions. |
