Abstract
Two-photon-induced fluorescence is observed from the photodynamic phyc obiliprotein phycoerythrin. Temporal, spectral, and intensity-dependen t properties of the two-photon-induced fluorescence emission from phyc oerythrin excited by a 1.06-mu m laser beam are reported. The measured two-photon absorption cross section of phycoerythrin is an order of m agnitude larger than that of Rhodamine 6G. The potential applications of phycobiliproteins for two-photon-induced fluorescence for microscop y of three-dimensional biological samples and three-dimensional optica l memory are discussed.
