“…This can be beneficial in applications where a specific beam profile or mode quality is required [11]. Increased Fiber Length: By adding an SMF, the overall length of the laser cavity is increased [12]. This can have an impact on the laser's performance, such as altering the threshold pump power required for lasing or affecting the laser's output power and efficiency.…”

Using erbium-doped fiber, a steady Q-switched erbium-doped laser (EDFL) was successfully demonstrated. With a 150 m of Single Mode Fiber to generate the Brillouin Fiber Laser and increase the non-linearity inside the cavity. In the absence of a Brillouin pump, a compact Brillouin fiber laser (BFL) is realized by combining an Erbium Doped Fiber (EDF) and a Single Mode Fiber (SMF), which serve as both the Brillouin and linear gain media. It is accomplished by self-Brillouin production in a laser cavity from 4.5 m of EDF and 150 m of SMF with strong nonlinearity. The SMF inside the ring cavity was used to generate self-generating BFL. The BFL in the linear cavity produced more Brillouin stokes at a lower pump threshold. In the experiments, the average of spacing is 0.088 nm was generated at the EDF pump power of 93.468 to 259.493 mW for the 150 m of SMF. This compact BFL has total cavity length (160.34 m). Eventually, this is the most recent gain medium length recorded for Brillouin erbium fiber laser production without the use of a Brillouin pump.

“…[18] Liu et al realized a triple Brillouin frequency spacing Brillouin fiber laser sensor for temperature measurement. [19] Desmond et al proposed a distributed forward Brillouin sensor based on light phase recovery. [20] It has been proved that both photons and phonons in opti-cal microfibers are strongly constrained and highly overlapped in space, [21,22] producing new type of BS driven by SAWs and HAWs.…”

Temperature and strain sensitivities of surface acoustic wave (SAW) and hybrid acoustic wave (HAW) Brillouin scattering (BS) in 1-1.3 μm diameter optical microfibers are simulated. In contrast to stimulated Brillouin scattering (SBS) from bulk acoustic wave in standard optical fiber, SAW and HAW BS, due to SAWs and HAWs induced by the coupling of longitudinal and shear waves and propagating along the surface and core of microfiber respectively, facilitate innovative detection in optical microfibers sensing. The highest temperature and strain sensitivities of the hybrid acoustic modes (HAMs) are 1.082 MHz/℃ and 0.0289 MHz/µε, respectively, which is suitable for microfiber sensing application of high temperature and strain resolutions. Meanwhile, the temperature and strain sensitivities of the SAMs are less affected by fiber diameter changes, ranging from 0.05 to 0.25 MHz/℃/µm and 0.0001 to 0.0005 MHz/µε/µm, respectively. It can be found that that SAW BS for temperature and strain sensing would put less stress on manufacturing constraints for optical microfibers. Besides, the simultaneous sensing of temperature and strain can be realized by SAW and HAW BS, with temperature and strain errors as low as 0.30-0.34 ℃ and 14.47-16.25 µε.

“…With this ultranarrow linewidth BFLs may find applications in microwave photonics [5] or in ultrahigh-resolution spectral analysis [6]. Similarly, multiwavelength Brillouin fiber lasers (MWBFLs) with several kinds of cavity configurations have been proposed [7][8][9][10] and are not only considered as a potential robust laser source for dense wavelength division multiplexing communication systems but can also be applied in sensing [11][12][13]. The standard architecture of a BFL consists of launching the light from a pump laser into an optical fiber loop-cavity to generate the SBS, in which the output is the Stokes component contained in the SBS spectrum that propagates in the opposite direction of the pump.…”

“…On the other hand, there are several other applications whose interest is to maximize the Brillouin gain. These include Brillouin fiber amplifiers (BFAs) [27][28][29], BFLs [5,6], and Brillouin fiber sensors [11][12][13]30]. Suppressing or increasing the Brillouin gain can be accomplished not only by changing the pump power but also by controlling ∆υ p .…”

Brillouin fiber lasers (BFLs) are a promising optical source technology for industrial and academic purposes that have experienced continuous progress in recent years. Currently, part of this development is focused on delivering laser solutions with low resonator loss, relatively low pump threshold, high efficiency, very small linewidth, and multi-wavelength architecture. In this perspective, this study employs an accurate numerical model based on an analytical solution to investigate the effect of the pump’s spectral linewidth on BFLs working both in single and cascaded multi-wavelength configurations. Output powers, thresholds, and the Stokes lines number simulated are analyzed here using a standard single-mode optical fiber as the Brillouin gain medium. The numerical results obtained not only allow identifying the regions of the pump’s spectral linewidth in which there is greater, moderate, or even no suppression of the stimulated Brillouin scattering inside the laser cavity but also provides a deep understanding of the internal dynamics of the BFLs cavities.
