We present results on the first demonstration of self-sweeping effect in a ring Er-doped fiber laser. Reverse self-sweeping (with decreasing wavelength) in a range of ~0.1 nm was obtained. Typical sweeping rate was 4 pm/s, which is sufficiently slower as compared with earlier reported fiber lasers. Dual longitudinal mode self-sweeping (similar to reported earlier in linear cavity Er-doped fiber laser) is obtained. The laser generates sequentially long overlapping pulses. Frequency of each subsequent pulse increases by one inter-mode spacing. However, the typical duration of dual-mode operation is ~10 ms, which is one order longer than in previous works. We demonstrated that increase in pump power causes deceleration of sweeping and elongation of dual-mode pulses up to 500 ms. The developed source can be used for fiber sensor interrogation.
