Femtosecond laser thermal reflection method has become an important experimental tool for studying the transient heat conduction in metals. We measured several Au films with different thicknesses using Front heating-Rear detecting method and obtained the propagation speed of electron temperature oscillation. The measured value agrees with the theoretical prediction of two-temperature model. The deep research into transient heat conduction process in metals is necessary for thermal design of microelectronic devices and development of femtosecond laser machining.
