Tunable Narrow Linewidth Erbium-Doped Fiber Ring Laser Based on Saturable Absorber and Self-Injection Feedback

Tunable Narrow Linewidth Erbium-Doped Fiber Ring Laser Based on Saturable Absorber and Self-Injection Feedback

We demonstrate a tunable single-longitudinal-mode (SLM) narrow linewidth erbium-doped fiber (EDF) ring laser (EDFRL) in a cost-effective way. The laser incorporates an unpumped-EDF-based saturable absorber (SA) and a self-injection feedback loop for mode selection. The EDFDRL exhibits linear tunabil...
