Abstract

Nonlinear refraction and scattering effect properties of C60/toluene solution were studied by using the Z-scan technique and 532 nm laser delivering 4 nanosecond (ns) pulses. With single ns pulse, reverse saturable absorption (RSA) and negative nonlinear refraction were observed, and the nonlinear scattering effect in the solution could not be ignored when the pulse energy was large enough. The refraction cross-section of the singlet and triplet excited-state were calculated as,, respectively. The nonlinear scattering coefficient was also obtained. PACS: 42.65.Dr; 42.65.Jx; 42.65.Hw
