The thermal diffusivity of YBa2Cu3O7-x (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 ± 0.05 mm2 s-1. The obtained result is compared to previous reports measured using various methods.
