Popis: We investigate experimentally laser annealing of oxide films on the sapphire surface at the LIMO 100-532/1064-U facility. The treatment is performed using a Nd:YAG solid-state laser of a fixed wavelength of 1,064 nm. We present the results of morphology studies of iron-oxide film surfaces by atomic force microscopy. We obtain the dependence of the film-surface peak height on the laser irradiation power. We show that a laser irradiation power of the order of 90 W is sufficient for the formation of crystal grains and transition to the polycrystalline structure of the film. We show that, depending on the laser-irradiation parameters, the film-surface quality can be refined due to the recrystallization of amorphous layers.
