“…In such a configuration, the linewidth of the oscillating mode is narrowed in the long SMF by the dynamic distributed feedback of its Rayleigh scattering [13]. The narrowed oscillating wavelength serves as the Brillouin pump P ω , which can pass the SMF in both directions.…”

We have proposed and demonstrated a novel multiwavelength Brillouin-erbium fiber laser (BEFL) with a linear cavity, in which, the Brillouin pump is self-excited within the cavity, doesn't require the injection from the external cavity or direct generation within the intracavity. In this scheme, more than 115 Stokes lines with relatively uniform amplitudes have been generated. The experiment also demonstrates that such a self-seeded BEFL performs good repetition and stability for both the operating wavelengths and the output power of each Stokes line. Meanwhile, the effect of the 980nm pump on the performance of the laser is investigated.

“…Only there were few BEFL working on the linear cavity [12] [13]. The linear cavity design exhibited low threshold power for the Erbium gain pumping, but the number of generated Stokes lines was limited at 22-line [13].…”

“…It has been used in optical fiber characterization [4], interferometric and distributed sensors [5], optical frequency metrology [6], narrowbandwidth application and perhaps most interest in SBS has arisen from the use of Brillouin gain generation in producing fiber laser with single [7] or multiple [8][9] wavelengths. In using SBS to create fiber laser, achieving a lower threshold value is one of the main important parameters of the fiber laser system [10]. Researchers have demonstrated significant interest in reducing Brillouin threshold in optical fibers.…”

<span>In this paper, two types of ring-cavity fiber laser structures that operate as a single wavelength laser were investigated on the threshold performance. The two structures are namely Brillouin fiber laser and Brillouin erbium fiber laser. In the first structure, the Brillouin pump signal was amplified before being injected into the laser cavity which namely as Brillouin fiber laser. Meanwhile, for second structure respectively, the Brillouin pump signal was pre-amplified in the laser cavity which namely as Brillouin Erbium fiber laser. We found that the stimulated Brillouin scattering threshold power was lowered significantly by circulating the spontaneous Brillouin scattering in the gain medium utilizing the pre-amplification technique. The optimum stimulated Brillouin scattering threshold power was about 1.4 mW, and this was achieved at optimum output coupling ratio of 95%. By comparing to the first structure in which the Brillouin pump signal was amplified before entering the laser cavity, stimulated Brillouin scattering threshold power was only achieved at 2.62 mW at a similar wavelength. The pre-amplification technique proposed in this paper has been shown to improve the performance of single-wavelength ring-cavity fiber lasers via significant reduction of the stimulated Brillouin scattering threshold power which was around 1.22 mW.</span>
