Abstract The 0.01M two-photon absorption dye trans-4-[p-(N-hydroxyethyl-N-methylamino)styryl]-N-methyl- pyridinium p-toluene sulfonate (abbreviated as HMASPS) doped polymer has been prepared. When pumped by the picosecond pulse from the pulsed mode-locked Nd:YAG laser, the polymer emits more intense upconverted fluorescence and superradiance compared to the solution sample of the dye. The two-photon pumped lasing with oscillating pulses has also obtained. Compared to the dye in its solution state, the emission spectra of the polymer are all blue-shifted. The polymer has a long upconverted fluorescent lifetime of about 4.041±0.04 ns.
