拉曼光纤激光:50年的历程、现状与趋势(特邀)

50^(th) anniversary of Raman fiber laser:History,progress and prospect(Invited)

自1972年Roger H.Stolen等人首次基于受激拉曼散射效应在玻璃光纤中实现激光输出以来,拉曼光纤激光技术已经走过了50年的发展历程。文中首先分阶段呈现拉曼光纤激光的发展历程,介绍具有里程碑意义的经典文献和重要技术突破,勾勒出拉曼光纤激光发展的概貌。其次根据拉曼光纤激光的研究现状,整理具有代表性的最新成果;介绍随机分布式反馈拉曼光纤激光、中红外拉曼光纤激光和超快激光等最新研究热点。最后梳理拉曼激光合束、半导体激光直接泵浦和非线性效应耦合新机制等方面的发展趋势。

The Raman fiber laser(RFL) has been developed for 50 years since the first laser generation in fiber based on stimulated Raman scattering in 1972 by Roger H.Stolen.Firstly,the development history of RFL was presented in stages.Through the introduction on classic milestone literatures standing for the significant technological breakthroughs,the general picture of the development of Raman fiber laser technology could be formed.Secondly,based on the recent status of RFL,the representative advanced achievements were selected,together with the novel research hotspots on the random distributed feedback Raman fiber lasers,middle-infrared Raman fiber lasers and ultra-fast fiber lasers.Finally,the future prospects of RFL were discussed,including the laser beam combination,laser diode directly pumped RFL and new mechanism on interactions among fiber nonlinear optics.
