A two‐photon 3D optical storage system based on a photochromic diarylethene (1,2‐bis(2‐methylbenzo[ b ]thiophen‐3‐yl)hexafluorocyclopentene) and a highly efficient two‐photon absorbing fluorescent dye (2,7‐bis[4‐(9,9‐didecylfluoren‐2‐yl)vinyl]phenylbenzothiazole) is demonstrated. The figure shows two‐photon fluorescent readout of data recorded by single‐photon excitation. The system is suitable for recording data in thick storage media and providing a non‐destructive readout method.
