Harmonically mode-locked fiber ring laser using a bismuth-based erbium-doped fiber and a bismuth-based highly nonlinear fiber

Abstract

We report a 10 GHz harmonically mode-locked short-cavity fiber laser using a bismuth-based erbium-doped fiber and a bismuth-based highly nonlinear fiber. Stable error-free operation is achieved for a 75 nm wavelength tuning range covering the CL-band.
