Metallic vanadium samples were oxidized in air by a cw Nd:YAG laser. The structure of developed V2O5 crystals was investigated by optical and scanning tunneling microscopy (STM). Ripple morphologies with submicron spatial period have been observed. The grating-like structures have been attributed to the interference of surface scattered electromagnetic waves with incident laser light. The dispersion of the surface capillary waves has been taken into account since the oxide has developed partly in a liquid phase.
