A simple fabrication of graphene-MoS2 nanocomposite, as well as individual graphene and molybdenum disulphide (MoS2) film has been done through a liquid phase exfoliation method using chitin as a binder. All of the developed films are integrated as a passive Q-switcher in an Erbium doped fiber laser. The graphene-MoS2 nanocomposite based passive Q-switcher is generated by a pulsed fiber laser with the shortest width of 1.63 µs and the highest signal to noise ratio of 51.01 dB. The graphene-MoS2 nanocomposite films show a better saturable absorption response compared to an individual graphene-chitin and MoS2-chitin based passive Q-switcher. Full Text: PDF ReferencesB.
