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

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

RIN transfer in random distributed feedback fiber lasers [PDF]
Optics Express, 2012 We numerically investigate relative intensity-noise transfer from a noisy pump to the generated Stokes component in random distributed feedback ultralong Raman fiber lasers. Results show transfer levels comparable to those in distributed Raman amplification and cavity-based ultralong Raman fiber lasers, but with some unique spectral features.

Narrow-band generation in random distributed feedback fiber laser [PDF]
Optics Express, 2013 Narrow-band emission of spectral width down to ~0.05 nm line-width is achieved in the random distributed feedback fiber laser employing narrow-band fiber Bragg grating or fiber Fabry-Perot interferometer filters. The observed line-width is ~10 times less than line-width of other demonstrated up to date random distributed feedback fiber lasers.
