提出了采用法拉第反常色散滤光器（ＦＡＤＯＦ）的光电双反馈激光信标新方案。该方案通过数字控制系统和光反馈系统的共同作用，使激光信标系统的稳定性、抗干扰性和可靠性大大提高，并实现了上电自动工作。这种新型激光信标的频率稳定度优于５×１０－９，在３０ｍｓ内可将半导体激光频率稳定在法拉第反常色散滤光器任一透射峰上。该方案可与采用法拉第反常色散滤光器的新型跟瞄系统匹配使用，对建立卫星激光通信链路有重要意义。
A new scheme of photoelectric double-feedback laser beacon using FADOF filter was proposed. The program through the digital control system and optical feedback system to work together to make the laser beacon system stability, anti-interference and reliability greatly improved, and to achieve the power automatically. The frequency stability of this new laser beacon is better than 5 × 10-9, stabilizing the semiconductor laser frequency on either transmission peak of the Faraday anomalous dispersion filter in 30ms. The scheme can be used with the new tracking system using Faraday anomalous dispersion filter, which is of great significance to the establishment of satellite laser communication links.
