摘　　要：光纤型Q开关是调Q全光纤激光器的关键部件。目前,可用的光纤型Q开关主要有基于SBS效应的被动Q开关、基于双光束干涉原理的主动Q开关和某些特殊设计的主动Q开关。基于SBS效应的被动Q开关存在重复频率不稳定且不易调节等缺点;基于双光束干涉原理的主动Q开关属于慢Q开关,其它主动Q开关的设计技术还不成熟,所以研究开发高性能的主动光纤型Q开关成为调Q全光纤激光器发展的必然要求。Fibered Q-switches are critical components of Q-switched all-fiber lasers. Presently, the useful fibered Q- switches mainly include passive Q-switches based on stimulated Brillouin scattering （SBS） effect, active Q-switches based on two-beam interference principle and some active Q-switches in special design. The repetition rates of the Q-switches based on SBS effect are not stable and adjustable. The Q-switches based on two-beam interference principle belong to slow Q-switches. Because the technologies of other active Q-switches are not yet mature, it is inevitable to develop active fibered Q-switches with high efficiency.
