In this paper, we propose and demonstrate experimentally a stable erbium-doped fiber (EDF) laser with single-longitudinal-mode (SLM) output by employing dual-ring structure. By using the multiple ring architecture, the densely spaced longitudinal modes would be suppressed and generated a SLM lasing output. In the measurement, the wavelength can be tuned in the wavelengths of 1530.0-1560.0 nm. And the measured output powers and side-mode suppression ratios (SMSRs) are between 5.2 and 14.1 dBm and 30.4 and 39.8 dB, respectively. In addition, the output stabilities of wavelength and power in proposed fiber laser have also been discussed.
