“…It can also contribute to stability by providing feedback and suppressing unwanted cavity fluctuations. Additionally, the SMF may introduce dispersion effects, which can influence the laser's pulse duration, chirp, or spectral width [21]. However, the specific impact of adding an SMF to a Brillouin fiber laser depends on factors like the SMF's properties, laser cavity design, and intended application [22].…”

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.

We demonstrated a compact multiwavelength Brillouin-erbium fiber laser (MBEFL) with quadruple-Brillouin-frequency spacing. The quadruple-Brillouin-frequency spacing multiwavelength is generated mainly by utilizing two four-port circulators, two coils of single-mode fiber and two erbium gain modules. The generated multiwavelength spectra were investigated through adjusting the Brillouin pump (BP) and the 980 nm pumps. In the experiments, eight stable wavelengths were produced and the wavelength spacing was 0.348 nm (about 43.5 GHz) as the wavelength and the power of the BP were 5 mW and 1548.11 nm respectively, meanwhile the two 980 nm pumps' powers were 470 mW and 520 mW respectively. The output multiwavelength can be tuned from 1546.12 nm to 1561.01 nm, and the maximum optical signal-to-noise ratio (OSNR) of the output channel was about 37 dB. The average OSNR of the stable multiwavelength was about 27 dB. The proposed stable and wider channel spaced MBEFL has diverse applications in dense wavelength division multiplexing optical communication, microwave photonics and fiber-optic sensors.

“…The wavelength division multiplexer (WDM) system requires multi-wavelength laser sources with equal-wavelength spacing, high optical signal to noise ratio (OSNR) [4], large number of channels, and high output uniformity over the channels spectra. Numerous methods have been reported to generate multi-wavelength combs in fiber lasers, such as four wave mixing [5], stimulated Brillouin scattering (SBS) [6,7] and nonlinear polarization rotation [8,9]. Among these technologies, multi-wavelength Brillouinerbium fiber laser (MBEFL) has attracted huge interest due to the inherent advantage of narrow linewidth and fixed Stokes lines spacing of about 0.088 nm [10,11].…”

We experimentally demonstrated a widely tunable multi-wavelength Brillouin-erbium fiber laser by utilizing a double-pass pre-amplification Brillouin pump (BP) within a single-linear laser cavity. Owing to this pre-amplification technique, the laser can operate at low pump power and exhibit a low threshold operation of 35 mW pump power to create the first Stokes signal. By adjusting the polarization controller (PC), self-lasing cavity modes' oscillation can be tuned over 10 nm from 1562 nm to 1572 nm. We experimentally showed that the proposed novel fiber laser structure can achieve up to ~33 output channels with a constant wavelength spacing of 0.088 nm at 7.4 dBm of BP power and 250 mW of the 980 nm pump power by varying the wavelength of the BP and adjusting the PC. In addition, an average of 32 stable output channels could all be tuned over 12 nm with an average optical signal to noise ratio of 25 dB.
