Abstract:Applying the D4σ-Z-scan technique with a laser delivering single pulses in the picosecond regime at 1064 nm, 532 nm, and 355 nm we report on the nonlinear (NL) optical properties of 5,10,15,20-Tetraphenyl-21H,23Hporphine (TPP) and 5,10,15,20-Tetraphenyl-21H,23H-porphine zinc (ZnTPP) solutions prepared in chlorobenzene. Accurate measurements of the NL coefficients for 4 concentrations in both compounds are provided. The results show no response in the IR for both materials, negative NL refraction for TPP in the… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
