Abstract

Watt-level erbium-praseodymium codoped ZBLAN midinfrared fiber laser with 100-nm continuously wavelength-tunable range (2.7-2.8 μm) is demonstrated. Continuous-wave output of >1 W with a line width of ~1.8 GHz over the entire tuning range is affordable. Owing to relatively small residual populations in the lower laser level 4I13/2 of Er ions in the Er-Pr-codoped system, the wavelength-tunable range shrinking with increasing pump power, which always happens in tunable singly Er-doped ZBLAN fiber lasers, was not observed in this tunable Er-Pr-codoped fiber laser.
