Abstract
The microscale heat conduction in an anisotropic thin-film subjected to an ultrafast laser heating is investigated. The coordinate transformation (CT) method has been employed to transform microscale heat conduction equations in an anisotropic thin-film to those of isotropic ones in the mapped domain. A comparison among three different models was made to investigate the effect of anisotropic thermal properties on the microscale heat conduction. Numerical results show that the CT method can be a good candidate to explore the microscale heat conduction mechanism in an anisotropic thin-film imposed by ultrafast pulse laser heating. The anisotropic heat conduction mechanism becomes more important when the thin film excited by multiple consecutive pulses with high power femtosecond laser. The multiple consecutive pulses with large separation time will spend much time to reach the thermal equilibrium state.
