Abstract
Large two-photon absorption cross section of a novel compound trans-1,3, 5- tri-(4-N,N-dimethylaminobenzylstyryl)-acetylacetone is measured to be sigma (2) = 8.4 x 10(-20) cm(4)/GW or o(2)' = 1.594 x 10(-47) cm(4)/(photon-s) b y using a 1064 nm Nd:YAG laser with 35 ps pulse width based on the intensit y-dependent transmissivity measurement. The frequency upconversion fluoresc ence is observed by two-photon laser pumping. This material is an ideal can didate for optical limiting and upconversion fluorescence.
