The effect of laser irradiation on amorphous films of anodic vanadium oxide was studied using a YAG:Nd³⁺ laser at wavelength 1.06 µm. Irradiation was found to lower the electrical conductivity of the oxide films and modify significantly the parameters of electroforming and switching in metal/oxide/metal sandwich structures. The threshold energy for laser modification was measured to be ~ 0.3 mJ/cm². It is shown that the changes of the electrical properties are associated with structural (crystallization) and chemical (in particular, the reduction V₂O₅ → VO₂) transformations and that non-thermal photo-stimulated effects play an important role in the laser modification of the vanadium oxide thin films.
