DPL在晶体体全息存储中引起的串扰问题研究

A Study on the Cross-talk Caused by DPL in Crystal Holographic Data Storage

本文采用半导体泵浦固体激光器 (DPL)取代 Ar+激光器作为晶体体全息存储系统的光源 ,针对其输出特性造成的串扰增强问题从实验和理论上加以分析 ,从而确定了 DPL的选择和改性的要求 ,最后给出了用 DPL为光源的多幅全息存储的实验结果。

Replacing the Ar + laser with the di ode-pumped solid-state laser (DPL) in the holographic data storage system is t he first step to make it compact.In this article,the increasing cross-talk caus ed by the application of DPL was analyzed experimentally and theoretically.The main reason of the phenomena is the multiple longitudinal modes in the output of the DPL.This result is helpful when choosing and improving the performance of the D PL.
