摘要

设计并搭建了一种支持百纳焦耳量级的单脉冲能量输出的锁模光纤激光器.激光器基于σ型腔结构,采用掺Yb偏振型大模场面积光子晶体光纤作为增益介质,利用半导体可饱和吸收镜实现自启动锁模.激光器内没有色散补偿机理,使其工作在全正色散锁模状态.通过在谐振腔内引入多通长腔使激光器的重复频率降低至11.1 MHz,直接获得了平均功率为1.08 W,单脉冲能量为 97 nJ,脉冲宽度为4.17 ps的稳定锁模脉冲输出,经腔外色散补偿,脉冲宽度压缩至740 fs.

Abstract

Pulse energy directly output from a mode-locked fiber laser approaching one hundred nanojoule is demonstrated. The fiber laser is based on a σ-shaped cavity design. A segment of single polarization Yb-doped large mode area photonic crystal fiber acts as gain medium. A semiconductor saturable absorber mirror is used for self-starting mode-locking operation. The fiber laser works in an all normal dispersion mode-locking regime with no intracavity dispersion compensation introduced in the laser. A long multi-pass cavity is used to reduce the repetition rate of the fiber laser. Direct output pulse energy of 97 nJ with an average power of 1.08 W is achieved at a low repetition rate of 11.1 MHz. The pulse duration is 4.17 ps,which can be extracavity dechirped to 740 fs.
