| Summary: | In this work, we have experimentally demonstrated the ultrafast laser in Erbium-doped fiber laser using MoS _2 as saturable absorber. The MoS _2 SA in this work is prepared by bottom-up method. A three-electrode configuration is used to perform the electrodeposition to coat the MoS _2 onto conductive film. The MoS _2 saturable absorber is incorporated into the fiber laser system to induce mode-locking operation centered at 1560.8 nm. The proposed saturable absorber has achieved pulse width of 1.47 ps, with highest average pulse energy of 0.44 nJ and repetition rate of 1.88 MHz. The venture of electrodeposition coated MoS _2 thin film as saturable absorber is potentially to pave the foundation toward the sustainable industry, innovation and infrastructure.
