“…The narrow linewidth is one of the advantages of Brillouin random fiber laser. [21][22][23] We use the non-zero delay selfheterodyne method based on acoustooptic modulator (AOM) to measure the linewidth of single BSL. The experimental setup for linewidth measurement is shown in Fig.…”

We present a Brillouin-Raman random fiber laser (BRRFL) with full-open linear cavity structure to generate broadband Brillouin frequency comb (BFC) with double Brillouin-frequency-shift spacing. The incorporation of a regeneration portion consisting of an Erbium-doped fiber and a single-mode fiber enables the generation of broadband BFC. The dynamics of broadband BFC generation changing with the pump power (EDF and Raman) and Brillouin pump (BP) wavelength are investigated respectively in detail. Under suitable conditions, the bidirectional BRRFL proposed can produce a flat-amplitude BFC with 40.7 nm bandwidth ranging from 1531 nm to 1571.7 nm, and built-in 242 orders Brillouin Stokes lines (BSLs) with double Brillouin-frequency-shift spacing. Moreover, the linewidth of single BSL was experimentally measured to be about 2.5 kHz. The broadband bidirectional narrow-linewidth BRRFL has great potential applications for optical communication, optical sensing, spectral measurement and so on.

“…Among all gain mediums of RFLs, the SBS process has unique merits, such as low threshold and narrow gain bandwidth, which favors developing RFLs with narrow linewidth. [ 16,21,22,165,174–177 ] In 2018, Popov et al. demonstrated a narrow‐linewidth half‐open short‐structure BRFL with an FBG array written in the fiber core and uniformly distributed over the length.…”

“…[6,7] At first, RFL was achieved by employing the combination of the Rayleigh backscattering induced by refractive index inhomogeneities and distributed amplification through the Raman effect, [7] which has then attracted extensive investigations into aspects of underlying physical mechanisms, output characteristics optimization, applications in various fields, etc. [8][9][10][11][12][13][14] With the unique feedback mechanism and 1D geometry, RFLs possess the advantages of both conventional fiber lasers and random lasers, such as low noise, [15][16][17] high efficiency, [18][19][20] narrow linewidth, [21][22][23] modeless, [15,24,25] etc. Particularly, significant advancements in the spectral properties of RFLs have emerged in the aspects of numerical modeling and physical mechanism investigation, lasing wavelength extension, spectrum manipulation, and the applications of spectral-tailored RFLs, etc.…”

Random fiber lasers (RFLs), a new variety of random lasers, have become a vigorous research spot over the past decades. RFLs possess superiorities in efficiency, structural flexibility, directionality, cost, etc. Particularly, RFLs are discovered to be good platforms for the construction of various forms of high‐performance lasers. Herein, recent progress in the spectral manipulation of RFLs and the applications of spectral‐tailored RFLs are reviewed. Both theoretical and experimental investigations of the unique spectral properties of RFLs up to now are presented. The superior wavelength flexibility of RFLs which can achieve any desired lasing wavelength in the 1–2.1 µm band is highlighted. Via spectral manipulation, RFLs have shown the capability of high‐spectral‐purity, narrow‐bandwidth, and multi‐wavelength output. Furthermore, the RFLs featuring unique spectral properties can lead to various promising applications, which are concisely summarized, including optical fiber communication, optical fiber sensing, imaging, supercontinuum generation, nonlinear‐frequency conversion, mid‐infrared lasing pump sources, and laser‐driven inertial confinement fusion motivation. The challenges and prospects for RFLs are also discussed.

“…Currently, the methods to achieve SLM fiber lasers are primarily categorized into three classes based on cavity structures: linear cavities, ring cavities, and composite cavities. The linear cavity structures primarily focus on two single-frequency short cavity structures: distributed Bragg reflectors and distributed feedback [8]. Short straight cavity structure has shorter cavity lengths and less flexibility [9,10].…”

This study presents a high-quality fiber ring laser created by integrating a semiconductor optical amplifier to generate amplified spontaneous emission with a four-subring resonator and utilizing the nonlinear polarization rotator effect. When the driven current of 400 mA, the laser exhibited a maximum power deviation of 0.204 dB and a wavelength deviation of 0.012 nm during a one-hour testing period. Furthermore, utilizing a delayed self-heterodyne measurement system, we measured the linewidth of the self-made fiber laser to be 23 kHz.
