We demonstrate a passive mode-locked Er:Yb doped double-clad fiber laser using a microfiber-based topological insulator (Bi(2)Se(3)) saturable absorber (TISA). By optimizing the cavity loss and output coupling ratio, the mode-locked fiber laser can operate in L-band with high average output power. With the highest pump power of 5 W, 91st harmonic mode locking of soliton bunches with average output power of 308 mW was obtained. This is the first report that the TISA based erbium-doped fiber laser operating above 1.6 μm and is also the highest output power yet reported in TISA based passive mode-locked fiber laser.
我们展示了一种使用基于微光纤的拓扑绝缘体（Bi₂Se₃）饱和吸收体（TISA）的被动锁模掺铒镱双包层光纤激光器。通过优化腔损耗和输出耦合比，该锁模光纤激光器能够在L波段以高平均输出功率运行。在最高泵浦功率为5 W的情况下，获得了平均输出功率为308 mW的孤子束91次谐波锁模。这是关于基于TISA的掺铒光纤激光器在1.6μm以上运行的首次报道，也是基于TISA的被动锁模光纤激光器中迄今报道的最高输出功率。
