摘要

本文提出了一种基于石墨烯涂层超细纤维的锁模光纤激光器。在光纤激光器稳定输出明暗孤子对的条件下，通过调节偏振控制器（PC）实现了双波长调谐，波长调谐范围为 11 nm。此外，还研究了偏振态对亮暗孤子的影响。研究表明，石墨烯锁模光纤激光器的锁模态可以在传统孤子和明暗孤子之间切换。通过调节 PC 和泵浦功率，可以获得不同形状和纳秒脉冲宽度的明暗孤子对。

Generation of mode-locked states of conventional solitons and bright-dark solitons in graphene mode-locked fiber laser.

This paper proposes a mode-locked fiber laser based on graphene-coated microfiber. The total length of the fiber laser resonant cavity is 31.34 m. Under the condition of stable output of bright-dark soliton pairs from the fiber laser, dual-wavelength tuning is realized by adjusting the polarization controller (PC), and the wavelength tuning range is 11 nm. Furthermore, the effects of polarization states on bright-dark solitons are studied. It is demonstrated that the mode-locking state can be switched between conventional solitons and bright-dark solitons in the graphene mode-locked fiber laser. Bright-dark soliton pairs with different shapes and nanosecond pulse width can be obtained by adjusting the PC and pump power.
