Laser-induced change in the refractive index in fullerene- and nanotubes-doped conjugated structures have been investigated by the dynamic holographic technique. Nonlinear refractive index n2 and nonlinear optical susceptibility χ(3) of the compounds have been calculated. The role of the high frequency Kerr photorefractive effect in the holographic grating recording under nanosecond laser irradiation has been discussed. A niche of the organic materials doped with nano-objects has been found among other nonlinear optical systems. The nano-object-stimulated improvement of laser strength of materials has been shown.

Optical limiting of the nanoobjects doped organic electrooptical materials have been studied in the visible and near infrared spectral range. It has been shown that the organic materials with nanoobjects can be used as nonlinear absorbers to protect human eyes and technical devices from high laser irradiation. The systems have been treated at the wavelength of 532, 633, 805, 1047, 1064, 1080, 1315, and 2940 nm. As an additional, the switching parameters of nanoobjects-doped liquid crystal compounds and improvement in the laser strength of the materials used as substrates for limiters and switchers have been shown.
