Abstract
A new dye Trans-4-[p-(N,N-diethylamino) styryl]-N-methylpyridinium iodide ( abbreviated as DEASMPI) has been synthesized. The two-photon absorption (TP A), TPA-induced frequency upconversion emission, and two-photon pumped (TPP ) frequency upconverted lasing properties of this new dye have also been ex perimentally studied. This new dye has a moderate TPA cross section of sigm a (2) = 6.9 x 10(-48) cm(4 .) s/phofon at 1064 nm, but exhibits a high lasi ng efficiency. The net conversion efficiency from the absorbed 1064-nm pump pulse energy to the 628-nm up-converted lasing energy is 3.2% at the pump energy level of 3 mJ.
