Ultra-broadband wavelength-tunable harmonically mode-locked fiber laser using a short length bismuth-oxide-based erbium-doped fiber

Abstract

We report a harmonically mode-locked fiber laser employing a 151-cm-long bismuth-oxide-based erbium-doped fiber. Near-transform-limited short pulses at 10 GHz are obtained with an ultra-broadband wavelength tuning range of 83 nm covering both the C-band and the L-band.
