摘　　要：随着激光器输出功率的不断提高.隔离器的研究意义显得日益重要。分别讨论了高功率光纤隔离器中隔离度与隔离功率的影响因素,通过精确调节法拉第旋转角和优化反向光路降低反向光热效应的方法分别提高了隔离度和隔离功率,并使高功率光纤隔离器的耐受隔离功率提高到了50 W。With the continuous im provem ent of laser output pow er,the research significance of isolator becomes increasingly im portant.The factors that affect the isolation ratio and isolation power in high-power fiber optical isolators are discussed separately.The methods of accurately adjusting the Faraday rotation angle and optimizing the reverse optical path to reduce the therm al effect of reversed light respectively increase the isolation ratio and isolation pow er,and the tolerance isolation power of the high-power fiber optical isolator has been increased to 50 W.

关 键 词：光纤隔离器 高功率 隔离度 隔离功率
