Abstract :
Summary form only given. The prospects of creating digital three dimensional (3D) optical-memory systems based on two-photon amplitude data writing with the use of femtosecond light pulses and fluorescent data reading are analyzed. A new variant of rewritable bit-by-bit single-beam two-photon writing and page-by-page fluorescent reading 3D optical data storage has been developed. The tabletop prototype for implementation of such a principle has been created. The polymeric multilayer matrices containing thin informative naphthacenepyridone (NP) doped layers separated by nonphotoactive layers are used as storage media.
