Abstract

We recently reported a new lasing dye, trans-4-[p-(N-ethyl-N- hydroxylethylamino)styryl]-N-methylpyridinium tetraphenylborate (ASPT), which has also been shown to possess a strong two-photon absorption (TPA) and subsequent frequency upconversion fluorescence behavior when excited with near infrared laser radiation. Based on the TPA mechanism, a highly efficient optical limiting performance has been demonstrated in a 2 cm long ASPT-doped epoxy rod pumped with 1.06 μm Q-switched laser pulses at 50-250 MW/cm² intensity levels. The measured nonlinear absorption coefficient reached 6 cm/GW for the tested sample of dopant concentration d₀=4×10 ^-3 M/L. The molecular TPA cross section of ASPT in the epoxy matrix is estimated as σ₂=2.5×10^-18 cm⁴/GW or σ₂^′=4.7×10^-46 cm ⁴/photon/s, respectively. Two-photon pumped cavity lasing is also observed in an ASPT-doped polymer rod.
