| 摘 要： | 啁啾光纤光栅可用于光纤色散补偿及脉冲压缩。该文从光纤光栅的耦合模方程出发，对中心波长为1053nm的啁啾光纤光栅进行了研究，数值分析了啁啾光纤光栅长度、耦合函数、啁啾系数、切趾技术等因素对啁啾光栅反射率、时延特性、色散特性、压缩特性的影响，并将结论应用于掺镱超短脉冲光纤激光器的设计，提出基于啁啾光纤光栅的全光纤环形腔连接方案。与其它非全光纤结构光纤激光器相比，这种结构具有更小的损耗和更高的效率。 |

| Abstract: | Chirped fiber grating can be used in compensating fiber dispersion and compressing pulse.With the coupled-mode theory,some parameters are analyzed, including grating length,coupled functions, chirped coefficient having relations with the reflectivity coefficient, time-delay character, dispersion and compression character. With the results , an Yb~(3 )-doped ultrashort pulse fiber laser is designed and an all-fiber ring cavity with chirped fiber grating is brought forward. Comparing with the other structures of the non-all-fiber lasers,the structure we designed is more efficient and has less power loss. |
| Keywords: | chirped fiber grating pulse compression ultrashort pulse Yb~(3 )-doped fiber fiber laser |
