Nonlinear optical properties of polymer-dispersed liquid-crystalline systems based on fullerene-doped 2-cyclooctylamino-5-nitropyridine

Holographic recording of thin diffraction gratings by nano-and picosecond laser pulses λ=532 nm) is studied in polymerdispersed liquid-crystalline structures based on photosensitive molecules of 2-cycloocty-lamino-5-nitropyridine sensitized with C70 fullerene. Using experimental data, nonlinear refraction n 2 and nonlinear third-order susceptibility χ(3) are calculated for the first time. The obained values determine the potential of the studied media for the modulation and frequency generation of laser radiation in the visible spectral range.
