We report the synchronization of two actively Q-switched fiber lasers operating at 1.5 μm and 2 μm with a shared broadband graphene electro-optic modulator. Two graphene monolayer sheets separated with a high-k HfO2 dielectric layer are configured to enable broadband light modulation. The graphene electro-optic modulator is shared by two optical fiber laser cavities (i.e., an erbium-doped fiber laser cavity and a thulium/holmium-codoped fiber laser cavity) to actively Q-switch the two lasers, resulting in stable synchronized pulses at 1.5 μm and 2 μm with a repetition rate ranging from 46 kHz to 56 kHz.
FingerprintDive into the research topics of 'Active synchronization and modulation of fiber lasers with a graphene electro-optic modulator'. Together they form a unique fingerprint.
