“…Random fiber lasers (RFLs) with distributed feedback media have attracted great attention since Ambartsumyan Basov proposed the study of substituting a scattering medium for one of the mirrors to generate a nonresonant-feedback laser with unique statistical properties in 1966 [1]. Unlike the traditional fiber laser utilizing fixed cavities restricting the spectrum and spatial mode, the nature of the output light in RFLs is determined by the disordered scattering caused by the scattering of nanoparticles [2], the distributed backward Rayleigh scattering originating from unavoidable refractive index inhomogeneities [3] or the random fiber gratings [4]. In recent years, attempts have been made by using diverse gain mechanisms, such as Raman scattering [5] and Brillouin scattering [6] both by various elemental excitations in the fiber medium, as well as rare-earth-doped fiber amplification [7], both in the linear open cavity and half-open configuration.…”

We proposed and demonstrated a high-efficiency Brillouin random fiber laser (BRFL) in a half-open linear random cavity incorporating with a self-inscribed dynamic fiber grating (DFG) for laser frequency stabilization. The DFG can be produced when the ion population distribution along erbium-doped fibers is periodically modulated by two coherent counter-propagating standing waves via the spatial hole-burning effect. Consequently, a BRFL with the linear half-open-cavity exhibited an optimized laser efficiency while the embedded DFG effectively purified the random modes and suppress the frequency drift caused by multiple random mode hopping. With a low laser threshold of 13.9 mW, the laser efficiency of up to 19.3% was observed, which is four times higher than that of the BRFL with a half-open ring cavity. It suggests that the proposed BRFLs could be beneficial to practical applications in fiber-optic sensing and coherent communication

“…Random lasers (RLs) have been the subject of intense research owing to their easy fabrication, low coherence, and small size [8][9][10][11][12][13][14][15][16][17]. The lasing feedback mechanism is synergistically achieved by multiple light scattering, which is different from traditional lasers [18][19][20][21][22][23][24][25][26][27].…”

In this paper, pure silk protein was extracted from Bombyx mori silks and fabricated into a new kind of disordered bio-microfiber structure using electrospinning technology. Coherent random lasing emission with low threshold was achieved in the silk fibroin fibers. The random lasing emission wavelength can be tuned in the range of 33 nm by controlling the pump location with different scattering strengths. Therefore, the bio-microfiber random lasers can be a wide spectral light source when the system is doped with a gain or energy transfer medium with a large fluorescence emission band. Application of the random lasers of the bio-microfibers as a low-coherence light source in speckle-free imaging had also been studied.

“…To solve two problems-high threshold and non-directivity-of random lasers (RLs), optical fibers have been used to confine the random laser system, bringing about the development of random fiber lasers (RFLs) [1]. Furthermore, a coherent RFL based on nanoparticles (NPs) scattering in the extremely weakly scattering regime has been obtained [2][3][4], which extends RFL from incoherent to coherent random lasing. To extend the application of RFL, D. V. Churkin and S. K. Turitsyn et al have demonstrated RFLs in the telecommunication fiber based on a random distributed feedback due to the Raman amplified Rayleigh backscattering [5,6].…”

We have demonstrated the realization of a high-polarization random fiber laser (RFL) output based on the hybrid Raman and Erbium gain with the tailored effect provided by a 45°-tilted fiber Bragg grating (45°-TFBG), revealing an improvement in the polarization extinction ratio (PER) and achieving a PER of ~15.3 dB. The hybrid RFL system incorporating the 45°-TFBG has been systematically characterized. The random lasing wavelength can be fixed under the extremely weak feedback effect of the 45°-TFBG with reflectivity of 0.09%. In addition, numerical simulation has verified that the weak feedback can boost the random lasing emission with fixed wavelength using a power balance model, which is in good accordance with the experiment results.
