主　　题：Q-switched mode-locked pulse graphene-deposited multimode microfiber multimode fiber laser 

摘      要：We report Q-switched mode-locked(QML)pulses generation in an Yb-doped multimode fiber(MMF)laser by using a graphene-deposited multimode microfiber(GMM)for the first time,to the best of our *** single-wavelength QML operation with the central wavelength tunable from 1028.81 nm to 1039.20 nm and the dual-wavelength QML operation with the wavelength spacing tunable from 0.93 nm to 5.79 nm are achieved due to the multimode interference filtering effect induced by the few-mode fiber and MMF structure and the GMM in the ***,in the single-wavelength QML operation,the fifth harmonic is also realized owing to the high nonlinear effect of the *** obtained results indicate that the QML pulses can be generated in the MMF laser,and such a flexible tunable laser has promising applications in optical sensing,measuring,and laser processing.
