Thermal contact resistance between thin ?lms was measured by the LPM. Empirical formulas of thermal contact resistance are given. The experimental error was analyzed. article info Article history: Received 21 April 2016 Revised 28 July 2016 Accepted 28 July 2016 Available online 21 September 2016 Keywords: Laser photothermal method Thermal diffusivity Thermal contact resistance Empirical formula abstract The Laser Photothermal Method (LPM), which is a transient non-contact technique, was employed to measure the thermal physical parameters of Stainless Steel 304 (SS304), Oxygen-Free Copper (OFC) and Aluminum Nitride (AlN) ceramics. The thermal diffusivity of SS304, OFC and AlN ceramic were measured by the LPM and some explanations for the tendency with the temperature were given. Compared with the reference values, it showed that the LPM is reliable in measuring thermal parameters. Following, the Thermal Contact Resistances (TCRs) of OFC-AlN ceramic, SS304-AlN, SS304-SS304 and AlN ceramic were measured in the temperature range from 70 K to 300 K and the contact pressure was on the order of 0.10 MPa. Some explanations were given to make clear the changing trend of TCRs with the increase of temperature. Moreover, some empirical formulas of the TCRs were established. The accuracy of the establishing empirical formulas had
