Abstract

Fullerene molecules (C⁶⁰, C⁷⁰, C⁷⁶) are known to posses unusual nonlinear optical response characteristics, which make them attractive for variety of applications, including optical limiters, recording media and switching devices [1-3]. These nonlinear properties are associated with the fullerene molecules having unique carbon-carbon single-and double bonds and combination of singlet- and triplet excited electronic states. Due to broad spectral range of the nonlinear response, fullerene-based materials may be used for recording of dynamic holograms from UV to near IR. In this paper we present results of experiments, where we study efficient self-diffraction from dynamic gratings recorded in C⁶⁰ solution in orto-xylene using excitation with energetic 150-fs-duration pulses at 780 nm wavelength.
