“…Thus, it is valuable to study the methods for realizing an EDFL with stable laser output and narrow linewidth. In order to improve the laser stability and guarantee SLM operation, techniques such as using a saturable absorber (SA), comb filter [14], fiber feedback loop (FFL) [15], and self-feedback light injection [16] are most commonly employed. In this study, an EDFL based on a fiber ring filter (FRF) has been constructed and investigated, and the FRF was composed of simple and all-fiber component.…”

In order to realize single longitudinal mode (SLM) output, an erbium-doped fiber (EDF) laser with fiber ring cavity is proposed which uses an un-pumped EDF saturated absorber as a SLM selector. Ring cavity length, coupler ratio and insertion loss which affect ring cavity filter performance are analyzed theoretically and simulated numerically. Un-pumped EDF length and Er3+ concentration are analyzed theoretically and simulated. Research shows that, the bigger coupling output ratio of ring cavity, the greater transmission peak; the greater mode line width; the shorter ring cavity length, the wider free spectral range; the bigger coupling loss, the smaller transmission peak; when the difference between two cavities length is big, cursor effect is not obvious. Laser threshold increases with absorber length increasing; the bigger saturated absorber concentration, the higher laser threshold.
