Ultrafast erbium-doped fiber laser using electrodeposition coated MoS2 thin film as saturable absorber

In this work, we have experimentally demonstrated the ultrafast laser in Erbium-doped fiber laser using MoS2 as saturable absorber. The MoS2 SA in this work is prepared by bottom-up method. A three-electrode configuration is used to perform the electrodeposition to coat the MoS2 onto conductive film...

Description
Summary:In this work, we have experimentally demonstrated the ultrafast laser in Erbium-doped fiber laser using MoS2 as saturable absorber. The MoS2 SA in this work is prepared by bottom-up method. A three-electrode configuration is used to perform the electrodeposition to coat the MoS2 onto conductive film. The MoS2 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 MoS2 thin film as saturable absorber is potentially to pave the foundation toward the sustainable industry, innovation and infrastructure.
