Abstract

The main goal of this paper is to analyze the corresponding relationship between the laser wavelength of the Erbium-doped fiber ring laser with the erbium-doped fiber length and coupler ratio. For the first time, this paper is based on the three-level rate equations, using analytical method, to research and achieve the corresponding relationships. Furthermore, gives the demonstration by experiment. The data of the laser wavelength changing with the erbium-doped fiber length and coupler ratio is achieved. The result shows, when the erbium-doped fiber length is increased, the laser wavelength is moved to the long wavelength, and when the laser wavelength is 1563nm the largest output power is obtained, the optimized erbium-doped fiber length is 11.5m. The phenomenon occurs that the coupler ratio is greater that the output wavelength of the laser is shorter. The result is meaningful for the optimized design of the tunable erbium-doped fiber laser by varying coupler ratio.
