Abstract

We measured the third-order optical nonlinearity of a pure C₆₀ solution and its derivative C₆₀-polyaminonitrile at 810 nm wavelength. The light source was a femtosecond Ti:sapphire laser. The light beam from the laser was split into two beams, a strong one and a weak one. Their intensity ratio was about 10:1. The strong one was used as a pump beam, which was polarized at 45° with respect to the weak one. The weak beam acted as a probe beam
