Abstract
A new dye trans-4-[p-(N-hydroxyethyl-N-methylamino)styryl]-N-methylpyridini um p-toluene sulphonate (abbreviated as HMASPS) was synthesized, the two-ph oton absorption (TPA), TPA-induced frequency upconversion emission, and two -photon pumped (TPP) frequency up-converted lasing properties of HMASPS wer e experimentally studied. This new dye has a moderate TPA cross-section of sigma (2) = 6.0 x 10(-48) cm(4) s photon(-1), but exhibits a high lasing ef ficiency. The net conversion efficiency from the absorbed 1064 nm pump puls e energy to the 630 nm up-converted lasing energy is 4% at a pump energy le vel of 4 mJ.
