We propose the holographic reciprocity effect (HRE) to describe the relationship between the exposure duration (ED) and the growth rate of diffraction efficiency (GRoDE) in volume holographic storage. The HRE process is investigated experimentally and theoretically in order to avoid the diffraction attenuation. Herein, introducing the medium absorption, we present a comprehensive probabilistic model to describe the HRE. PQ/PMMA polymers are fabricated and investigated to reveal the influence of HRE on the diffraction characteristics through two recording approaches: pulsed exposure with nanosecond (ns) level and continuous wave (CW) exposure at the millisecond (ms) level. We obtain the holographic reciprocity matching (HRM) range of ED in PQ/PMMA polymers with 10−6~102 s level and improve the response time to microsecond (μs) order with no diffraction deficiency. This work can promote the application of volume holographic storage in high-speed transient information accessing technology.

PQ/PMMA 聚合物中全息互易效应对衍射特性影响的理论和实验研究

我们提出全息互易效应 (HRE) 来描述体积全息存储中曝光持续时间 (ED) 和衍射效率增长率 (GRoDE) 之间的关系。为了避免衍射衰减，对 HRE 过程进行了实验和理论研究。在此，引入介质吸收，我们提出了一个全面的概率模型来描述 HRE。制造和研究 PQ/PMMA 聚合物，以通过两种记录方法揭示 HRE 对衍射特性的影响：纳秒 (ns) 级脉冲曝光和毫秒 (ms) 级连续波 (CW) 曝光。我们获得了 PQ/PMMA 聚合物中 ED 的全息互易匹配 (HRM) 范围为 10−6~102 s 级，并将响应时间提高到微秒 (μs) 级，没有衍射缺陷。该工作可以促进体全息存储在高速瞬态信息存取技术中的应用。
