First, a grating decay rate and a thermal diffusion rate of the transient gratings are determined out of the energy-time trace observed by using a transient grating technique with 266-nm laser pulse inducing transient gratings in a LaCoO3 thin film. Second, the grating models aimed at studying two different thermal diffusion phenomena in contrast with the previous paper are described. The difference between both phenomena is attributable to the volume of photon scattering to characterize induced transient gratings. It is concluded that a reliable energy-time trace is observed when the transient gratings with a thickness smaller than a film are induced on the very surface of a thin film sample.
