Fig. 1. MoSSe mechanical exfoliation process and deposition onto the fiber ferrule.

Fig. 2. Characterization of MoSSe SA Raman spectrum. The insets of Fig. 2 show (a) the linear absorption, (b) the non-linear absorption measurement, and (c) the microscope image capture of the SA.

Fig. 3. Setup of the proposed Q -switched YDF laser.

Fig. 4. Q -switched pulsed output at 1 μm, showing (a) the optical output as obtained using an OSA and a Q -switched pulse train obtained using an RFSA (inset) and (b) single-pulse RFSA and wide-band RFSA (inset).

Fig. 5. (a) Repetition rate and pulse width and (b) output power and pulse energy as a function of the rising pump power.
