Doc. ID 239686)Random fiber lasers blend together attractive features of traditional random lasers, such as low cost and simplicity of fabrication, with high-performance characteristics of conventional fiber lasers, such as good directionality and high efficiency. Low coherence of random lasers is important for speckle-free imaging applications. The random fiber laser with distributed feedback proposed in 2010 led to a quickly developing class of light sources that utilize inherent optical fiber disorder in the form of the Rayleigh scattering and distributed Raman gain. The random fiber laser is an interesting and practically important example of a photonic device based on exploitation of optical medium disorder. We provide an overview of recent advances in this field, including high-power and high-efficiency generation, spectral and statistical properties of random fiber lasers, nonlinear kinetic theory of such systems, and emerging applications in telecommunications and distributed sensing.

“…Several parameters and techniques have been recently tested to enhance the MBRFL performance parameters, such as the use of a hybrid gain medium, adding a large effective area fiber [18], or bismuthbased erbium-doped fiber [19]. Moreover, the halfopen cavity with a fiber loop mirror at the pump side [20] and spectral reshaping effect introduced by Rayleigh scattering [21] have been used to improve the flatness of the output spectrum.…”

Enhancing performance of multiwavelength Brillouin–Raman fiber laser by capturing residual pump power

We demonstrate a simple design to enhance the performance of a multiwavelength Brillouin-Raman fiber laser by capturing the residual Raman pump power (RPP) from the laser cavity using a wavelength-selective coupler. The performance parameters of the laser system are investigated and compared with the conventional design under the same input design parameters. Both laser systems at a RPP of 375 mW can generate up to 33 Stokes lines with an equal channel spacing of 0.08 nm; however, the tunability of the laser without injection of residual RPP is 25% higher than the conventional laser structure. In addition, for a laser system without residual RPP injection, increasing the RPP improves the laser performance and generates up to 42 Stokes lines with a tunability of 24.5 nm, from 1570 to 1594.5 nm, at 475 mW. In contrast, the laser system with a residual RPP has the worst performance as the pump power is increased, and generates only nine Stokes lines with a tuning range of 5 nm at the same RPP of 475 mW.

“…However, no obvious peak power discrepancy between the odd and even Stokes lines was observed in Ref. [22], [23] and [26], which employed a half-open cavity to generate multiwavelength fiber lasers. In this paper, no obvious peak power discrepancy between the odd and even Stokes lines was observed by replacing the full open cavity with a linear half-open cavity incorporating a CFBG.…”

“…Shargh et al combined dispersion compensating fiber (DCF) with a large effective area fiber to achieve low peak power discrepancy of about 2.3 dB between the odd and the even channels [18], but at the expense of noise on each Stokes line, marked by two or three peaks for each channel. Wu et al proposed a multiwavelength BrillouinRaman random fiber laser with an half-open cavity by using a fiber loop mirror to overcome the discrepancy in power level between neighboring channels [22]. Cholan et al employed a ring cavity at one end of the DCF to form a half-open cavity and lowered the peak power difference between the first and the fifth output channel to 4.59 dB, which was explained to contribute to four wave mixing (FWM) in DCF [23].…”

We experimentally demonstrate a multiwavelength Brillouin-erbium random fiber laser with a linear half-open cavity, by combining Rayleigh scattering with the reflection of a chirped fiber Bragg grating. The linear half-open cavity configuration is successful in obtaining multiwavelength random fiber laser with flattened output spectra, which is verified by both about 4.3 dB peak power difference between the first and fourth channel and inconspicuous peak power discrepancy between the odd and even Stokes lines. Up to five output channels with a spacing of about 0.088 nm, a linewidth of about 0.02 nm and optical signal-to-noise ratio over 15 dB have been obtained.
