Abstract
A passively mode-locked thulium-doped fiber laser using a tungsten ditelluride saturable absorber (WTe2-SA) is demonstrated. High-power mode-locked pulses with an average output power of 108.1 mW were achieved by incorporating the WTe2-SA into a thulium-doped fiber oscillator. To the best of our knowledge, this is the highest average power obtained from a WTe2-SA-based fiber laser. We further amplified the output power to 5.60 W with an all-fiber thulium-doped double-cladding fiber amplifier. Our result indicates that WTe2-SA could be an excellent candidate for a high-power fiber laser system. (C) 2019 Optical Society of AmericaFunding Information
