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 σ2=8.4 x 10-20cm4/GW or σ'2=1.594 x 10-47cm4/(photon.s) by using a 1064 nm Nd:YAG laser with 35 ps pulse width based on the intensity-dependent transmissivity measurement. The frequency upconversion fluorescence is observed by two-photon laser pumping. This material is an ideal candidate for optical limiting and upconversion fluorescence.
