Abstract

Triple different operation regimes like passive Q-switched (PQS), Q-switched mode-locking (QSML) and continuous-wave mode-locking (CWML) are experimentally observed as progressive pulse dynamics in a mode-locked fiber laser, which is constructed with several-meters of cascaded small-core erbium/bismuth co-doped fiber (EBCF) to engineer the cavity loss modulation. The pulse fission evolution from PQS to QSML to CWML operation is flexibly achieved through pump power variation as the only control parameter at fixed polarization orientation. Output characteristics in all triple operation regimes are studied in detail and particularly the pulse transitional process between PQS and QSML is reported experimentally for the first time, to the best of our knowledge. The laser pulse formation criteria for different operation regimes are also theoretically analyzed. The obtained results and analysis disclose the complete pulses evolution process from PQS to QSML to CWML operation, which contribute to further understanding of the complex laser pulses evolution dynamics and formation mechanism in a passively mode-locked fiber laser.
