Few-layer ReS2(1-x)Se2x nanoflakes for noise-like pulse generation in mode-locked ytterbium-doped fiber laser

Abstract

We fabricated the tenary ReS2(1-x)Se2x and investigated few-layer ReS1.02Se0.98 nanoflakes to realize the passively Q-switched and noise-like pulses operating at 1μm wavelength.Stable Q-switching pulses can be achieved with a threshold pump power of 180 mW and a maximum pump power of 300 mW. The single pulse energy of 81.47 nJ and pulse width as narrow as 2.2 µs at 1035 nm center wavelength were achieved. By optimizing the parameter in the cavity, self-started noise-like pulses was realized, which are centered at 1031nm.The average pulse width of the spike was 283 fs on the top of a broad pedestal and the fundamental repetition was 38.98MHz. It is demonstrated that ReS2(1-x)Se2x has potential applications in ultrafast photonics.
