Abstract
One‐photon and two‐photon spectroscopic properties of a novel two‐photon dye doped polymethylmethacrylate (PMMA) were reported. High‐density three‐dimensional (3D) optical data storage was achieved by photobleaching two‐photon fluorescence in the dye‐doped PMMA film with data storage storage density as high as 14 Gbits/cm^3^ theoretically. Photobleaching decay kinetics at different excitation intensity reveal that the mechanism of two‐photon photobleaching process concerns the action of three photons.
