Temperature distribution within and outside the laser heating zone

The article considers a mechanism for temperature distribution within metal surfaces subjected to laser irradiation as well as zones not affected by laser light. It is shown that the growth of the laser heating zone facilitates more even temperature distribution. Under an alternate laser pulse at a shorter distance, the temperature of the surface increases; it is added up to the residual temperature of the previous laser pulse, and then slowly decreases. All this stabilizes the residual voltage within metals.
