In this work, a pulsed laser was achieved through mode -locking in a Thulium/Holmium co-doped fiber laser (THDFL) utilizing a saturable absorber (SA) made of reduced graphene oxide/magnesium oxide (rGO/MgO) composite. The composite material was first synthesized using a simple hydrothermal method wi...
