Summary: Antimonene was used as a saturable absorber to generate an ultrafast mode-locked and Q-switched laser in the 2 μm wavelength region. Two antimonene-based saturable absorbers were prepared and inserted into a thulium-holmium-doped fiber laser to produce pulsed laser. Antimonene coated onto a tapered fiber generated soliton mode-locked pulses, while thin-film antimonene was used for Q-switched pulse generation. The mode-locked laser had a pulse width of 1.3 ps and a repetition rate of 12.6 MHz, while the Q-switched laser operated at a wavelength of 1890.1 nm with a repetition rate of 56.63 kHz and a pulse width of 2.85 μs, allowing for wide-range tunability within the wavelength range of 1882 nm-1936 nm.
