Abstract :
We have measured the real components of the third-order optical nonlinearity of organometallic compound films of C60M2 (M=Pd, Pt, and Sm) by using the femtosecond optically heterodyned optical Kerr effect at 647.0 nm. The results show that there is an enhancement of the real components of the third-order optical nonlinearity of C60M2 films compared to that of pristine C60 film. We attribute the origin of this enhancement to the charge transfer from the metal atoms to the C60 molecules.
