Experiment of porous material heated by microsecond laser pulse and the corresponding theoretical analysis are carried out. Some non-Fourier heat conduction phenomena are observed in the experimental sample. The experimental results indicate that only if the thermal disturbance is strong enough (i.e. the pulse duration is short enough and pulse heat flux is great enough), it is possible to observe apparent non-Fourier heat conduction phenomenon in the sample and evident non-Fourier heat conduction phenomenon can only exist in a very limited region around the thermal disturbance position. The hyperbolic heat conduction (HHC) equation and the dual-phase lag (DPL) model are employed respectively to describe the non-Fourier heat condution process happening in the experimental sample and the finite difference method (FDM) is used to solve them numerically. The numerical solutions show that both the HHC equation and the DPL model can predict the non-Fourier heat conduction phenomenon emerging in the experimental sample qualitatively. Moreover, if τq and τT are assumed suitable values, the theoretical result of the DPL model is more agreeable to the experimental result.
