The thermal diffusivity of YBa 2 Cu 3 O 7รx (YBCO) film was measured using the optical pump-probe method. A theoretical finite-difference model was employed to calculate the diffusivity value, and the best fit for the c-axis oriented YBCO film showed an average thermal diffusivity of 0.25 ยฑ 0.05 mm
The non-destructive and non-contact photothermal beam deflection method has been applied to thin synthetic diamond films to give thermal conductivity measurements. The thickness of the diamond film was 12-50 /zm on silicon and tungsten substrates. The maximum film thermal conductivity value obtained
