A thin metal film irradiated by multiple laser pulses is considered. The microscale heat transfer in the domain considered is described by hyperbolic two-temperature model. This model contains two energy equations determining the heat exchange in the electron gas and the metal lattice. The problem is solved by a explicit scheme of finite difference method. The influence of separation time between two laser pulses on the electrons and lattice temperatures is discussed.
