Abstract

The fullerene-doping effect on spectral and nonlinear optical properties of (pi) -conjugated organic systems based on 2-cyclooctylamino-5-nitropyridine, 2-(n-prolinol)-5- nitropyridine, N-(4-nitrophenyl)-(L)-prolinol, and polyimide 6B has been investigated. Under nanosecond laser irradiation at the wave length of 532 nm, reverse saturable absorption has been examined. To clarify peculiarities of optical laser power limiting, the reverse saturable absorption, the Foerster mechanism, two-photon and free-carrier absorption, as well as the complex formation must be taken into consideration. The compounds investigated have been found to be efficient absorbers and they could be applied to limit the laser irradiation at the energy density of more than 4-5 J/cm^-2.
