Paper Abstract

The two-photon excitation of hypocrellin A (HA) was examined at 800 nm. The two-photon excited fluorescence spectrum of HA was very similar to those obtained by one-photon excitation no matter whether or not the HA was dissolved in air-saturated or air-free solutions. The result showed that the two-photon induced photodynamic processes of HA will be almost the same as one-photon induced photodynamic processes. The two-photon excitation cross section of HA was measured at 800 nm as about 34.8 x 10-50 cm4s/photon .The large two-photon cross section of HA, suggested that the HA can be a potential two-photon phototherapeutic agent.
