ABSTRACT Based on monolayer MoTe2 film, we have proposed a mode-locked fibre laser delivering single-wavelength and dual-wavelength solitons at the telecommunication band. The saturable absorber (SA) is synthesized by coating monolayer MoTe2 film on the pinhole of fibre pigtail. The experimental results show that our soliton lasers can work at the single- and dual-wavelength states, respectively, by appropriately adjusting the polarization controller. The proposed laser can work stably at the mode-locking state for several hours, indicating that monolayer MoTe2 film is an excellent SA material for ultrafast optics.

具有基于 MoTe2 的可饱和吸收器的可切换双波长超快光纤激光器

摘要 基于单层 MoTe2 薄膜，我们提出了一种锁模光纤激光器，可在电信波段提供单波长和双波长孤子。可饱和吸收体（SA）是通过在尾纤的针孔上涂覆单层 MoTe2 薄膜合成的。实验结果表明，通过适当调整偏振控制器，我们的孤子激光器可以分别工作在单波长和双波长状态。所提出的激光器可以在锁模状态下稳定工作数小时，表明单层 MoTe2 薄膜是一种用于超快光学的优秀 SA 材料。
