MoWS for Q-switched pulse generation in ytterbium-doped fiber laser.

In this work, we fabricate the MoWS by microwave-assisted solvothermal method, and report the Q-switched Yb-doped fiber lasers (YDFL) using MoWS polymer film and tapered fiber as the saturable absorbers (SAs). The modulation depth and saturable intensity of the film SA are 5.63% and 6.
