中文摘要：
基于光致漂白的双光子吸收三维光信息存储原理,以钛蓝宝石飞秒脉冲激光在一种新型光致漂白材料芴类衍生物BMOSF中进行光致漂白双光子信息写入和读出的实验研究,实现了6层光信息存储,信息点间距和信息层间距分别为8和10μm;采用MATLAB软件对6层信息点进行信号强度识别和信号点强度对比。实验表明,芴类衍生物BMOSF可以用于双光子三维光存储,为多层高密度和超高密度光信息存储材料研究打下了坚实的基础。
英文摘要：
According to photobleaching three-dimensional（3-D） optical information storage theory of two-photon absorption,the Ti：Sapphire femtosecond pulse laser was used as writting beam and readout beam of two-photon 3-D optical storage.The writting and readout experiment for two-photon photobleaching in the new material consisting of BMOSF fluorene derivatives was carried out,and six-layer optical data storage was realized.The distance between two adjacent bits in each layer is 8 μm and the interval between two adjacent layers is 10 μm.Using MATLAB software,the intensity of six-layer signal was identified and the signal intensity of contrast was achieved.The experiment proves that BMOSF fluorene derivatives can be used for two-photon 3-D optical storage,which has laid a foundation for the multi-layer high-density and ultra-high density optical information storage materials research.
