Abstract

In recent years, transition metal dichalcogenides (TMDs) have been widely used as saturable absorbers (SAs) in ultrafast fiber lasers. Among them, we have chosen manganese sulfide (MnS), also a type of TMD, for its small bandgap and excellent nonlinear optical properties. In this paper, we have fabricated a MnS thin film as a saturable absorber and demonstrated a passively Q-switched erbium-doped fiber laser based on MnS. It has achieved stable short-pulsed output. With a pump power of 29.8 mW from a 980 nm semiconductor laser, we obtained stable Q-switched pulses at a center wavelength of 1563.3 nm with a repetition rate of 29 kHz. The 3-dB spectral bandwidth is 1.25 nm, and the pulse width is 7.15 μs. The average output power is 0.95 mW, and the pulse energy is 32.8 nJ. The signal-to-noise ratio of the RF spectrum at the fundamental frequency is 54 dB, indicating the high stability of the Q-switched pulses. These results demonstrate that MnS, as a promising new SA material, provides a new research approach for generating stable short-pulsed output. Additionally, this is the first proposal of using MnS as a saturable absorber in Q-switched fiber lasers.
