A possibility to form tree-dimensional 10Tb-density optical memory based on permanent modification, or damage, of transparent dielectrics, using powerful femtosecond laser pulses has already been demonstrated by the Applicants. This project aims to improve the fundamental understanding of ultrafast laser formation of nano-bits using unique ability of photorefractive materials to reversible change and the refractive index. We aim to find ways for controlling the storage time, density and the writing-reading-erasing rate without inducing damage in the material. The results will be applied to efficient formation of high-speed, high density, write-read-erase 3D optical memory for applications in the information technology.

本申请人已经证明了使用强大的飞秒激光脉冲基于透明介质的永久性修改或损坏来形成三维10 Tb密度光学存储器的可能性。 本项目旨在利用光折变材料独特的可逆变化能力和折射率，提高对超快激光形成纳米比特的基本理解。 我们的目标是找到控制存储时间，密度和写入-读取-擦除速率而不引起材料损伤的方法。 研究结果将被应用于信息技术应用中的高速、高密度、写-读-擦3D光学存储器的有效形成。
