Studies of optical limiting with C60 in KBr and C60 thin film on optical glass

The optical limiting behavior has been first observed for C60 solution in toluene and in polymethyl methacrylate by Lee W. Tutt et al and A. Kost et al respectively. In order to make the possible use of the optical limiting in practice, we have studied the optical limiting of Q- switched Nd:YAG radiation at 532 nm using the C60 in KBr as a solid host and the C60 thin film on optical glass. The experimental results for the C60 in KBr show that the threshold power of the optical depends on the concentrations of the C60 in KBr, and the solid KBr-C60 is induced optical damaged as the input fluence reach to 0.7 J/cm2. The experiment results for the C60 thin film on optical glass show that the optical limiting behavior is not obvious, and the C60 film is be induced optical damaged when the input fluence is greater than 0.55 J/cm2.
