摘　　要：法拉第激光器是一种利用法拉第反常色散原子滤光器作为选频元件的新型外腔半导体激光器,原理上法拉第激光的输出波长随着激光二极管驱动电流及工作温度的变化,始终与原子跃迁谱线相对应,可以将激光频率有效地锁定至原子跃迁谱线,实现窄线宽的激光输出信号,并且短期与长期频率稳定性均较好。本文详细介绍了自1845年法拉第旋光效应提出以来,法拉第反常色散原子滤光器的发展历程,法拉第激光器的工作机理、发展历程以及性能优越性,并结合国内外的研究进展,介绍了法拉第激光发展各个阶段的技术瓶颈及相应的解决办法,同时展望了法拉第激光器未来在量子领域特别是量子精密测量领域的重要价值。Faraday laser is a novel external cavity diode laser(ECDL)that uses the Faraday anomalous dispersion optical filter as the frequencyselective element.In principle,the changes of Faraday laser output wavelength with the laser diodes'temperature and current always corresponds to the atomic transition lines.The laser frequency can be effectively locked to the atomic transition spectral line,achieving a narrow linewidth laser output signal.Both shortterm and longterm frequency stability are good enough for some applications.The development process of Faraday anomalous dispersion optical filters,and the mechanism,development process and advantages of Faraday lasers are summarized in this paper since the Faraday effect was reported in 1845.Combined with the research results at home and abroad,the technical bottlenecks and corresponding solutions belonging to different stages of Faraday laser development are introduced.The important value of Faraday laser in the quantum field,especially in the field of quantum precision measurement,in the future is also anticipated.
