Abstract

We present experimental results on optical limiting in C₆₀ and C₇₀ solutions in various organic solvents using 30 ns pulses at 527 nm. Angular and temporally resolved measurements of transmitted light and the solvent dependence of optical limiting suggest that in C₆₀ solutions the optical limiting is dominantly of thermal origin. Results of z-scan are presented which show contribution to limiting action from nonlinear refraction as well as scattering. The relevance of these findings to DFWM experiments with visible laser pulses is also discussed.
