Passive mode-locking is achieved at a 28 MHz repetition rate, generating 1.7 ps optical pulses, while active mode-locking is demonstrated at repetition rates of 4 GHz and 10 GHz. This work demonstrates the potential of scalable graphene-based saturable absorbers for fiber laser locking and paves the way for future fully integrated mode-locked laser systems.Journal article10.1038/s41598-025-93051-zWOS:001449065600001SATURABLE ABSORBERLAYER GRAPHENEHIGH-SPEEDPHOTONICSMEDLINE:40102548
