Laser Interference Metallurgy has been used to modify locally microstructure and mechanical properties of metallic thin films with spatial periodicity. Irradiating Platinum films using a Nd:YAG pulsed laser enables the fabrication of three different microstructural architectures. Texture analyses have proven the corresponding impact on the microstructure and the anisotropy of periodic structures. Nanoindentation tests demonstrate an increase of hardness in the microcrystalline region according to the inverse Hall‐Petch effect.
