摘      要：The 0.01M two-photon absorption dye trans-4-[p-(N-hydroxyethyl-N-methylamino)styryl]-N-methyl-pyridinium p-toluene sulfonate (HMASPS) doped polymer has been prepared. Whenpumped by the picosecond pulse from the pulsed mode-locked Nd:YAG laser, the polymer emits more intense upconverted fluorescence andsuperradiance compared to the solution sample of the dye. The two-photon pumped lasing with oscillating pulses has also beenobtained. Compared to the dye in its solution state, the emission spectra of the polymer are all blueshifted. The polymer has a longupconverted fluorescent lifetime of about4.041±0.04ns
