Paper Abstract

A new dye Trans-4-[p-(N,N-diethylamino) styryl]-N- methylpyridinium iodide (abbreviated as DEASMPI) has been synthesized. The two-photon absorption (TPA), TPA-induced frequency up- conversion emission, and two-photon pumped (TPP) frequency up- converted lasing properties of this new dye have also been experimentally studied. This new dye has a moderate TPA cross section of ?2 = 6.9x 10-48 cm4.s/photon at 1064-nm, but exhibits a high lasing 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.
