Comparison of optical power limiting in carbon-black suspensions C60 in toluene and C60 in chloronaphthalene at 694 nm

摘要

Abstract: This paper presents the results of a comparison study among three carbon-based solutions: a carbon-black suspension, C$-60$/ in toluene, and C$-60$/ in chloronaphthalene. The carbon-black suspensions were used as baseline samples for comparison with the C$-60$/ solutions and were fabricated with the same transmission at 694 nm as the C$-60$/ samples. A ruby laser operating both with and without the Q-switch was used in this study. The limiting results of the C$-60$/ materials are compared with the predicted results from a five-level model previously used to calculate the optical limiting performance of C$-60$/ at 532 nm. !6
