1.36-kW Spectral-Narrowing Fiber Laser Seeded by Random Fiber Laser
IEEE Photonics Technology Letters, 2019A single-mode 1.36-kW output power fiber amplifier with 0.22-nm full-width at half-maximum (FWHM) is realized by employing a master oscillator power amplifier (MOPA) configuration, seeded by a random fiber laser (RFL). We demonstrated an approach of narrowing the emission spectrum of the fiber amplifier by lengthening the passive fiber in the seed ...

Tunable multiwavelength Brillouin random fiber laser
2018 Asia Communications and Photonics Conference (ACP), 2018A novel tunable multiwavelength random fiber laser with half-open cavity has been demonstrated, which is formed by total reflection of a connected 3 dB coupler and randomly distributed Rayleigh scattering in single mode fiber. Seven Stokes lines have been achieved.

Towards high-power random fiber laser
SPIE Proceedings, 2014Study on random laser is an interesting topic in physics. In this paper we pay much attention to the high power random laser achievement in optical fiber. Two kinds of optical gains are used for light amplification. One is Raman gain and the other is Yb-doped fiber gain.

Linearly polarized low-noise Brillouin random fiber laser
Optics Letters, 2017A linearly polarized Brillouin random fiber laser (LP-BRFL) with distributed feedback along 2 km polarization-maintaining fibers (PMFs) is demonstrated. The laser was built up using a bidirectional pumping mechanism in an all-PMF configuration, yielding a radiation with 8% power efficiency and more than 25 dB polarization extinction ratio.
