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