Paper Abstract

Two-photon single beam multi-layer writing and scanning confocal reading are performed in anthracene derivatives membrane by Ti:sapphire femtosecond laser and three-dimensional scanning confocal system. And a good result is achieved, Two-photon excitation can be produced inside the anthracene derivatives membrane, where is 100 μm from the surface of the recording material. The wavelength of the laser is 726 nm(363nm×2). The size of recording spot along longitidunal direction is less than 2 μm, and that along lateral direction is less than 1 μm. The signal keeps clear definition after many times of reading out, when the power of the reading laser is less than 5 mW.
