    Experimental optimization in terms of power stability and output power of highly Er-doped fiber lasers with single and hybrid cavities
    (Taylor & Francis, 2010) Pérez Herrera, Rosa Ana; Chen, Shuying; Zhao, Weizhong; Sun, Tong; López-Amo Sáinz, Manuel; Ingeniería Eléctrica y Electrónica; Ingeniaritza Elektrikoa eta Elektronikoa
    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.

    Influence of saturable absorbers on fiber ring laser sensors
    (SPIE, 2017) Rodríguez Cobo, Luis; Quintela, M. A.; Ruiz Lombera, Rubén; Pérez Herrera, Rosa Ana; López-Amo Sáinz, Manuel; López Higuera, José Miguel; Ingeniaritza Elektrikoa eta Elektronikoa; Institute of Smart Cities - ISC; Ingeniería Eléctrica y Electrónica
    In this work, a fiber ring laser sensor has been employed to analyze the influence of passive Er-doped fiber acting as saturable absorber. Lasing modes of fiber ring lasers can be reduced by properly locating a saturable absorber that narrows the spectral width of the FBG that selects the lasing wavelength. Employing commercial Er-doped fiber, different configurations have been evaluated, reaching the SLM regime on a ring cavity of several meters. Thus, the achieved strain response of the whole sensor behaves at its mirror FBG, exhibiting linear response to strain.
