Abstract

A broadly tunable erbium-doped fiber ring laser is investigated through theoretical modeling and experiment. A numerical model based on an iterative solution of propagation rate equations is used to analyze the dependence of laser output power on total intracavity loss and output couple ratio. The numerical results are in good agreement with the experimentally obtained data. The results indicate that minimization of the intracavity loss as well as optimization of the output coupling ratio is very important. A S+C+L band tunable range which covering 135nm is achieve. This fiber ring laser has a flat, stable output spectra and better than 60 dB signal-to-ASE-noise ratio.
