Principles and progress of the coupled cavity fiber laser

概述耦合腔型(俗称8字型)光纤激光器基本原理的基础上,分析了非线性光纤环形镜(NOLM)、非线性放大环形镜(NALM)和色散非均衡光纤环形镜(DI-NOLM)这3种主要的8字型光纤激光器的技术原理和相关研究进展。讨论了8字型光纤激光器在光子晶体光纤介质、多波长和有理数谐波锁模方向的最新研究进展,并总结了8字型光纤激光器当前的研究重点和技术发展前景。

Based on the summary of the main characteristics of figure eight fiber laser, technical principles and research progress of three main schemes including nonlinear optical loop mirror （NOLM）, nonlinear amplification fiber loop mirror （NALM） and non-equilibrium dispersion nonlinear optical loop （DI-NOLM） are analyzed in the paper. Finally, latest research progress of figure eight fiber laser in direction of photonic crystal fiber media, multi-wavelength and rational harmonic mode-locked are discussed, and the current research focus and technology development prospects is summarized and concluded.
