| Abstract: | Heat conduction in thin metal film irradiated by short-pulse laser was carried out using a conional stable finite difference scheme,which involved the generalized dual-phase-lagging heat condition model(DPL). Various behaviors of thermal response in thin metal film were exhibited by adjusting the relaxation parameters and the characteristics of the microscale thermal response were discussed under the donditions of various character times of laser and various thickness of metal film. |
