Sumario:In this article, the output power stability of several different highly erbiumdoped fiber ring lasers, as a function of the laser parameters, is experimentally investigated. The study is focused on the optimization of several key parameters (erbium-doped fiber length, pump power, and different laser configurations) without changing the basic scheme. The results obtained show that the laser configuration plays an important role in achieving stable multi-wavelength lasing at room temperature in the erbium-doped fiber ring lasers. For an optimized configuration, these power fluctuations are lower than 0.08 dB, showing a notable improvement compared with previously presented work where the output power variations were about 0.2 dB. These lasers have the advantage of a simple all-fiber configuration, low cost, high stability, and operability at room temperature.
