Abstract: In this paper, realization the effect of increasing frequencies for the Nd:YAG laser pulse ablation technique in water was studied With the stability of energy and wavelength of the laser used, where the wavelength used was 1064 nm and a fixed energy of 300 mille joules per pulse and two different frequencies for each sample. The first frequency is 6 Hz and the second frequency is 10 Hz the effect of increasing the frequency on the size of the oxides of Vanadium nanomaterial prepared by the laser ablation method, we studying the properties of the Vanadium oxide the temperature was raised to above 600o C by the calcination process inside the thermal ovens for a period time about four hours for each sample, which led to the arrangement of the atoms inside the crystal lattice and obtaining a consistent structural arrangement the optical properties were studied by UV-Visible light were determined The absorption ranges of the materials as well as energy band gaps, studying the crystal structure of the material using X-ray diffraction, describing the surface structure and the shape of the particles formed during the preparation process using FE-SEM.
