Refractive Index of Organic Systems Doped with Nano-Objects

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 n 2 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.
