Development of a single mode narrow linewidth composite cavity fiber laser

In this project, the effectiveness of incorporating composite cavity technique into the design of an Erbium-doped fiber laser (EDFL) in achieving single mode narrow linewidth operation is being investigated. An all-fiber compound ring laser is formed by inserting a dual coupler fiber ring into the m...
