Random distributed feedback fiber laser of ultimate efficiency [PDF]
Advanced Photonics, 2014 We demonstrate a random fiber laser of ultimate efficiency. More than 2 Watts are generated from 0.5W of pump excess over the generation threshold. At higher power, an optical efficiency corresponds to the quantum limit.

Power optimization of random distributed feedback fiber lasers
Optics Express, 2012 We present a comprehensive study of power output characteristics of random distributed feedback Raman fiber lasers. The calculated optimal slope efficiency of the backward wave generation in the one-arm configuration is shown to be as high as ~90% for 1 W threshold.

Temporally Stable Random Fiber Laser Operates at 1070 nm
IEEE Photonics Journal, 2015 We experimentally demonstrate a temporally stable random fiber laser (RFL) operating at 1070-nm wavelength. A piece of 25-km passive fiber pumped by a 1018-nm ytterbium-doped fiber laser provides both Raman amplification from stimulated Raman scattering ...

Random lasing in a short Er-doped artificial Rayleigh fiber
Results in Physics, 2020 We report on random lasing observed with 5-m-long Er-doped fiber comprising an array of weak fiber Bragg gratings (FBGs) inscribed in the fiber core and uniformly distributed over the whole fiber length.

Efficient 1054 nm Raman Random Fiber Laser
Photonics, 2023 Low–coherence laser is regarded as the key to mitigating laser–plasma instability (LPI) in laser–driven inertial confinement fusion (ICF), where LPI can decrease the laser energy coupled to the target.

Narrow-linewidth Q-switched random distributed feedback fiber laser
Optics Express, 2016 A narrow-linewidth Q-switched random fiber laser (RFL) based on a half-opened cavity, which is realized by narrow-linewidth fiber Bragg grating (FBG) and a section of 3 km passive fiber, has been proposed and experimentally investigated. The narrow-linewidth lasing is generated by the spectral filtering of three FBGs with linewidth of 1.21 nm, 0.56 nm,
