我们回顾了玻璃与强超短激光脉冲的相互作用，揭示了由纳米结构自组织介导的可重写 5D 光学存储器和偏振成像滤波器的新现象和最新演示。特别是，我们通过实验验证了线偏振强超短脉冲可以基于光子和电子等离子体之间的干涉来控制均匀介质中局部光学各向异性的方向。这些所谓的“纳米光栅”由光致氧缺陷组成，在多个激光脉冲的过程中出现，并且垂直于激光偏振方向。表现出形式双折射的纳米光栅结构已经从残余双折射随着缺陷形成阈值的降低演变为氧缺陷的自组装。
We review the interaction of glass with intense ultrashort laser pulses revealing new phenomena and recent demonstrations of rewritable 5D optical memory and polarization imaging filter mediated by the self-organization of nanostructure. Particularly, we experimentally verify linearly polarized intense ultrashort pulses can control the direction of local optical anisotropy in homogeneous medium based on the interference between photon and electron plasma. These so-called “nanogratings” composed of the photoinduced oxygen defects emerge in the course of multiple laser pulses and are oriented perpendicularly to the laser polarization direction. The nanograting structures, which exhibit form birefringence, have evolved from residual birefringence along with lowering threshold for defect formation into self-assembly of oxygen defects.
