Temporal Profiles

Abstract: Harmonic self mode-locking effects are observed in heavily doped fiber lasers operating near 3 μm. The temporal profiles for the output of an Er-ZBLAN fiber laser operating at ~2.7 μm and an Ho, Pr-ZBLAN fiber laser operating at ~2.87 μm are reported. Stable second harmonic mode-locking is observed in the Er-ZBLAN fiber laser under 970nm pumping for an Er concentration of 50000 ppm, while unstable harmonic mode-locking of order of between 1-1/7 times the round cavity round trip time was observed for the higher concentration of 80000 ppm and for all pump powers. Unstable harmonic mode-locking is observed in the Ho, Pr-ZBLAN fiber laser when pumped at 1064nm, for fiber lengths up to 13m and for all pump powers. The experimental mode-locked pulse train periods are found to be consistent with theoretical analysis. The origin and properties of harmonic self mode-locking in heavily doped ZBLAN fiber lasers operated near 3 μm are discussed.
