Spectral correlations in a random distributed feedback fibre laser [PDF]

open access: yesNature Communications, 2017
The feedback mechanism in random fibre lasers has been insofar deemed incoherent. To reveal the dynamic evolution of the random fibre laser spectra, Sugavanamet al.

Effect of Linewidth on the Relative Intensity Noise in Random Distributed Feedback Raman Fiber Lasers [PDF]

open access: yesSensors, 2022
We experimentally explore the relation between spectral linewidth and RIN transfer in half-open cavity random distributed feedback Raman lasers, demonstrating for the first time the possibility of adjusting the pump-to-signal RIN transfer intensity and ...

TUNABLE ULTRA-LONG RANDOM DISTRIBUTED FEEDBACK FIBER LASER [PDF]

open access: yesJurnal Teknologi, 2016
A 72 km open-ended symmetrical tunable random distributed feedback fiber laser (RDB-FL) with different pumping schemes is presented in this study. The random distributed feedback was contributed by Rayleigh scattering in the single-mode fiber while distributed gain was provided by the effect of stimulated Raman scattering.

Direct measurements of localized spectral modes in random distributed feedback fiber laser

open access: yesResults in Physics, 2021
We present observation of ultra-narrow spectral modes in the generation of the random fiber laser by using a technique of optical heterodyning in real-time. We found that such modes have a spectral width below 3 MHz. The modes are spatially extended over

Switchable Wide-Band Multi-Wavelength Brillouin-Erbium Fiber Laser Based on Random Distributed Feedback

open access: yesIEEE Access, 2020
A wavelength-interval switchable wide-band multi-wavelength Brillouin-erbium fiber laser with a half-open cavity is proposed and experimentally demonstrated, which is constructed by random distributed feedback (RDFB) mirrors provided by Rayleigh ...

Single-Frequency Ring Fiber Laser with Random Distributed Feedback Provided by Artificial Rayleigh Scattering

open access: yesPhotonics
Femtosecond (fs) laser inscription technology allows for the production of in-fiber disordered structures with an enhanced level of Rayleigh backscattering with relatively few induced losses. These properties enable the application of these structures as

Comprehensive Investigations on 1053 nm Random Distributed Feedback Fiber Laser

open access: yesIEEE Photonics Journal, 2017
We design a 1053 nm Yb3+-doped random fiber laser (YRFL) based on the combination of Yb3+ -doped fiber (YDF) and single mode fiber (SMF), in which the YDF provides active gain, while SMF offers random distributed feedback.
