Abstract
A new dye Trans-4-[p-(N-hydroxyethyl-N-ethylamino)styryl]-N-methylpyridiniu m p-toluene sulfonate {HEASPS) was synthesized, and the two-photon absorpti on {TPA), TPA-induced frequency up-conversion emission, and two-photon pump ed (TPP) frequency up-converted lasing properties of this new dye were expe rimentally studied. This new dye has a moderate TPA cross-section of sigma (2)=4.7 x 10(-48) cm(4). s/photon at 1064 nm, but exhibits a high lasing ef ficiency. The net conversion efficiency from the absorbed 1064 cm pump puls e energy to the 626 cm up-converted lasing energy is 18.2% at the pump ener gy level of 1.9 mJ.
