摘要： An optical data storage medium is provided. The optical data storage medium includes a polymer matrix; a reactant capable of undergoing a change upon triplet excitation, thereby causing a refractive index change; and a non-linear sensitizer capable of absorbing actinic radiation to cause upper triplet energy transfer to said reactant. The refractive index change capacity of the medium is at least about 0.005. The non-linear sensitizer comprises a triarylmethane dye.

摘要： Disclosed is a method of producing a hologram through a two-beam laser interfering exposure process, which comprises emitting a coherent laser light with a pulse width (τ) ranging from greater than 900 femtoseconds to 100 picoseconds and a laser power of 10 µJ/pulse or more using a solid-state laser as a light source, dividing the pulses light from the laser into two beams, controlling the two beams temporally and spatially in such a manner that the two beam are converged on a surface of or inside a workpiece for recording a hologram while matching the respective converged spots of the two beams with one another temporally and spatially to create the interference therebetween so as to record a surface-relief hologram on the surface of the workpiece or an embedded hologram inside the workpiece in an irreversible manner. The present invention can solve a problem with a conventional process of recording a hologram in a non-photosensitive material in an irreversible manner using interfering femtosecond laser pulses, specifically, distortion in the waveforms of pulsed laser beams and resulting instability in recording of an embedded hologram due to a non-linear optical interaction between the femtosecond laser pulses and air/the material.

摘要： There are provided a recording material for holograms characterized by low corruption of recorded data with time, a manufacturing method thereof, a recording medium for holograms, a hologram recording method and a hologram reproduction method. The recording material for holograms of this invention comprises a metal oxide porous body provided with an oxygen donor substance in the pores. In the recording material for holograms, recording is accomplished by increasing the oxygen content of the metal oxide porous body with oxygen from the oxygen donor substance produced upon irradiation of recording light. The irradiated sites undergo no further alteration even with additional light irradiation, and the heat-induced volume fluctuations are negligible. The recording material for holograms exhibits reduced corruption of recorded data with time when subjected to repeated reproduction or when the recorded medium is stored for long periods.

摘要： The invention relates to a holographic data-storage medium (1'), comprising a polymer film (2), which acts as a storage layer, can be modified locally by heating and is configured as the cover layer of the data-storage medium (1'). An absorbent layer (4) comprising an absorbent dye is provided below the polymer film. Said absorbent dye is designed to at least partially absorb a recording beam that inputs information and to at least partially release the heat thus produced locally to the polymer film (2). In advantageous embodiments of the data-storage medium (1'), a layer of adhesive material (6) is provided below the absorbent layer (4) and a partially permeable reflective layer (8) is located between the polymer film (2) and the absorbent layer (4).
