Two-photon three-dimensional optical storage of a new pyrimidine photobleaching material

Two-photon three-dimensional high-density optical storage is an important method of optical storage. Based on two-photon absorption three-dimensional optical information storage principle of light-induced bleaching, the storage information is written and readout by using titanium sapphire femtosecond pulsed laser, the experiment of the storage information written and readout is carried out in a novel photobleaching material pyrimidines, six layers storage information is achieved, information point spacing is 4 μm and the information layer spacing is 12 μm. The signal strength information of six layers information is recognized using MATLAB software. And the experiment of the stability of the pyrimidine photobleaching material is carried out, experimental results indicate that the material has good stability. The experiments show that the pyrimidine photobleaching materials can be used for two-photon three-dimensional optical storage, which has laid a solid foundation for multi-layer high density and high density optical information storage materials research.
