• two-temperature model
• laser-metal interaction
• Anisimov and Nolte models

We used a new approach to describe the laser-metals thermal interaction based upon the two-temperature (electron and phonon) model. Using only one Fourier equation, we got information about 3D thermal field, surface temperature, and steady state quantum effects during laser irradiation of metals. To this purpose, we applied the integral transform technique to the Anisimov and Nolte models. As an example, we computed the surface temperature in laser-Au thin film interaction during multi-pulse nanosecond laser ablation of the metal.
