摘要
依据光折变晶体中自抽运与互抽运相位共轭共存的特性,提出了一种新型的光折变自适应光外差探测系统,并利用相干性较差的固体激光器进行了自适应光外差探测的实验研究.该系统具有结构简单、干扰小和外差探测灵敏度高等优点,在光通信、激光雷达等许多领域内都具有重要的实用价值.
Abstract
Based on self-pumped and mutually pumped phase conjugation coexsisting in the photorefractive crystal, a new photorefractive adaptive optical heterodyne detection system is proposed and experimentally implemented with a solid-state laser of poor coherence. The proposed system features simple structure, low noise and high responsivity. It will have a variety of potential applications in optical communication and laser radar.
