Abstract

This paper presents the results of a comparison study among three carbon-based solutions: a carbon-black suspension, C<SUB>60</SUB> in toluene, and C<SUB>60</SUB> in chloronaphthalene. The carbon-black suspensions were used as baseline samples for comparison with the C<SUB>60</SUB> solutions and were fabricated with the same transmission at 694 nm as the C<SUB>60</SUB> samples. A ruby laser operating both with and without the Q-switch was used in this study. The limiting results of the C<SUB>60</SUB> materials are compared with the predicted results from a five-level model previously used to calculate the optical limiting performance of C<SUB>60</SUB> at 532 nm.
