Abstract :
The present study reports on the experimental investigation of the nonlinear optical response of polydispersed and ultradispersed diamond powders and onion-like carbon structures in water suspension. It has been found that the onion-like carbon structures exhibit much stronger optical limiting action compared with the diamond powder suspensions. It is also shown that under our experimental conditions the nonlinear refraction of the onion-like structures was negligible.
