摘要：

We have demonstrated the realization ofwavelength-tunable pulse outputs in a mode-locked fiber laser by utilizing 2D MoTe2 film as the saturable absorber (SA). The SA is synthesized by coating 2D MoTe2 film on the pinhole of the fiber pigtail and it can work stably at the mode-locking state for several weeks, indicating that the 2D MoTe2 film is a suitable SA for ultrafast optics. The MoTe2 film mode-locked fiber laser can operate well at a wide spectral band, and the central wavelength of pulses is tunable in the range from 1530 to 1560 nm, which is attributed to the polarization-sensitive feature of the proposed SA. Our new SA will benefit high-power pulsed lasers, materials processing, and frequency comb spectroscopy. (C) 2019 Optical Society of America
