Abstract
We present and demonstrate a stabilized and selectable erbium-doped fiber (EDF) ring laser according to the proposed EDF saturable absorber (SA) and self-injected method to achieve single-longitudinal-mode (SLM) output and narrow the laser linewidth simultaneously. The 60-nm continuous wave (CW) tunability range from 1525.0 to 1585.0 nm is also accomplished here. Moreover, the output performance of wavelength stability and laser linewidth are also performed experimentally.
