In this study, a mode-locked, Thulium-doped fiber (TDF) laser operating in the 2.0-mu m wavelength region and using an iron phosphorus trisulfide (FePS3) overlay with a polymercoated on an arc-shaped fiber was successfully demonstrated. The mode-locked pulses were generated at a central wavelength of 1935.7 nm and a 3-dB bandwidth of 2.68 nm. Its soliton-like nature was validated by the presence of Kelly's sidebands in the observed optical spectrum. The maximum repetition rate of the TDF mode-locked laser was 10.95 MHz, with a pulse width of 1.47 ps. The generated mode-locked output has significant stability, with no observable shifts in the central wavelength or Kelly's sidebands over the measurement time due to the polymer's protective layer. The experimental results show that a polymer-coated FePS 3 arc-shaped fiber can be used as a SA device to produce stable and long-term mode-locked pulses in the TDF-based fiber laser.
