Based on the two-temperature theory,a numerical model to solve the heating process at surface vicinity irradiated by ultrashort pulse laser is established to investigate the influence of temperature-dependent coupling of material on temperature field in metal Au irradiated by ultrashort pulse laser.Taking account of the temperature-dependent properties of material and the spatial and temporal shape of the laser pulse,the transient temperature fields by ultrashort pulse laser in metal（Au）is numerical simulated by the finite element method（FEM）.The difference of temperature fields from considering and neglecting the temperature-dependent coupling of material is compared,and the lattice temperature distribution in the vicinity of laser-irradiated region at different depths and at different radial distances are obtained.The numerical results indicate that the temperature-dependent coupling affects not only the electron and lattice temperature rising speed and temperature maximum but also the spatial distribution of temperature field.This study establishes a theory basis for stress field and ultrasound field in metal generated by femtosecond laser.
