摘　　要：光纤激光器的相干合成是获得高功率、高亮度激光的有效方法之一。概述了近年来主动锁相光纤放大器相干合成技术的发展状况,主要介绍了目前采用的自适应锁相、外差锁相和自参考锁相三种锁相技术,对其工作原理、技术途径与特点进行了分析和比较,并对构建主动锁相光纤放大器相干合成系统需注意的几点提出建议。Coherent combination of fiber lasers is one of the effective technique to achieve high power and high brightness laser beam. Active coherent combination techniques of fiber amplifiers in recent years are reviewed. Three kinds of phase locking technique are investigated, including adaptive phase-locking, heterodyne phase-locking and self-referenced phase-locking techniques. The principle and technique of these three techniques are studied and their strengths and weaknesses are pointed. Further some suggestions for active coherent combination system are proposed.
