Résumé en anglais

We experimentally demonstrate a passively mode-locked Er:Yb doped double-clad fiber laser usinga graphene nanocoated optical taper. Averaging 20lm of clad diameter with a length of 6 mm,such a saturable absorber enables a strong light–graphene interaction owing to the evanescent fieldof the excited cladding mode. With the highest pump power of 5 W, the 326th harmonic mode lock-ing of soliton bunches with an average output power of 520 mW was obtained in a fiber ring cavitythat has a fundamental frequency of 1.67 MHz. This is the highest average output power yetreported in graphene-based passively mode-locked fiber lasers.
