Paper Abstract

The nonlinear optical properties are reported for a novel organic dendrimer using femtosecond pulses. The organic dendrimer showed strong nonlinear refraction when measured at 790 nm, a wavelength far from the linear resonance. The nonlinear refractive index was measured by the z-scan technique and the magnitude was measured to be 1.1*10-4 cm2/GW. The presence of two photon absorption was observed and a related nonlinear absorption coefficient was found to be 1.2*10-2 cm/GW. A strong two-photon luminescence was detected resulting from this nonlinear absorption, and the power dependence and spectral characteristics were measured. The presence of a higher order, (chi) (5), nonlinear optical effect was also detected. The ultra-fast dynamics of the organic dendrimer using fluorescence upconversion spectroscopy are reported. At higher emission energies we observe femto-second decay, and at lower energies a rise time of the luminescence intensity was observed.
