英文摘要	An optical data storage system and method with non-destructive multiple readout of 3-D data stored in multiple layers uses two-photon induced fluorescence modulation. The novel system uses the photochromic properties of the open and closed form of diarylethene in the two-photon energy transfer-based read-out method of a 3-D optical data storage system, providing more than 10,000 readout cycles without significantly compromising the stored data. The system of the present invention can be recorded and read out using the same wavelength simply by changing the intensities. Also, since the incident intensity used in two-photon readout is low due to the efficient absorption of the two-photon absorbing fluorene dye, a less expensive, nanosecond laser diode can be used, making this two-photon 3-D data storage system less expensive, stable, highly responsive, and reliable. This photochromic system is capable of either write-once read many (WORM) or erasable and rewritable 3D optical data storage.
