Passively mode-locked thulium-holmium co-doped fiber laser using hybrid side polished fiber with MoWS2-rGO nanocomposite

Passive mode-locking pulse generation in a Thulium-Holmium doped fiber laser (THDFL) with molybdenum tungsten disulfide-reduced graphene oxide (MoWS2-rGO) nanocomposite saturable absorber (SA) was demonstrated for operation in 2.0 mu m wavelength regions. Mode-locked pulse was achieved by the evanes...
