The ΓΏrst operation of cavity lasing of a two-photon absorption (TPA) organic dye, trans-4-[p-(N -ethyl-N -hydroxyethylamino) styryl]-N -methylpyridinium iodide (HEASPI), by using picosecond infrared laser as pump source is reported in this paper. Temporal proΓΏle of cavity lasing shows obvious oscill
