摘要：

Third-harmonic generation (THG) with a two-photon-absorption (TPA) type resonance was used to monitor the J-aggregation of ethyl thiacarbocyanine in aqueous solution. Correlations between TPA-resonant THG and two-photon-excited photoluminescence are revealed, indicating the significance of excited states for non-linear-optical processes in J-aggregating solutions. Similar to Raman resonances in coherent anti-Stokes Raman scattering, TPA resonances in THG allow THG enhancement to be effectively decoupled from the growth of radiation losses.
