Paper Abstract

We report two separate studies of the nonlinear optical properties of unique fullerene materials. Degenerate four- wave mixing measurements of the endohedral metallofullerene Er2 at C82 at 1064 nm show that the third order susceptibility is increased by more than two orders of magnitude relative to the empty cage fullerenes as a result of the metal-to-cage charge transfer. Optical limiting studies of C60 derivatives and higher fullerenes in the 680 to 880 nm spectral region demonstrate that these materials are strong reverse saturable absorbers at wavelengths where C60 itself is transparent. The tremendous variety of available fullerene-derived structures provides important opportunities for optimization of nonlinear optical responses.
