中文摘要：

与目前广泛使用的锁模器相比，碳纳米管饱和吸收体具有超快恢复时间（100fs）、宽带宽、高光损伤阈值、易制作以及与光纤和纳米器件兼容等优点。对基于碳纳米管的饱和吸收体的超短脉冲光纤激光器进行综述，针对目前存在的问题，指出了其发展方向。

英文摘要：

Carbon nanotubes have outstanding optical properties over the existing mode lockers including ul- trashort recovery time （-100fs）, wide operating bandwidth, high optical damage threshold, easy manufacturing, as well as excellent compatibility with fibers and nanodevices. In this paper, the ultra-short pulse fiber lasers using carbon nanotubes as saturable absorber are reviewed, and the future development is recommended based on the current situation of the problems existed in the area.
