Abstract

The paper reports on the investigation of the nonlinear optical properties of nanosized grains of Fe(IO₃)₃, recently synthesized with a simple and inexpensive process. The measurements have been carried out using a Ti:sapphire femtosecond oscillator coupled to an inverse microscope modified to detect the polarization dependence of the signal. It is shown that Fe(IO₃)₃ crystals (20-70 nm) can be efficiently employed as local probes for second-harmonic generation (SHG) microscopy, owing to their high nonlinear coefficients.
