In this paper experimental results concerning far field diffraction of Fe3O4 nanoparticles produced by ablating iron target in distilled water using the first harmonic of an acousto-optically Q-switched Nd:YAG laser are presented. In the present research we measured nonlinear refractive index of Fe3O4 nanoparticles using a single beam z-scan technique to compare with the results of far field diffraction. In both experiment we used a He-Ne CW laser beam operated at 632.8 nm to obtain nonlinear refractive index of Fe3O4 nanoparticles.
Keywords: Far Field Diffraction, Nonlinear Refractive index, Laser Ablation, Fe3O4 nanoparticles
