Comprehensive Investigations on 1053 nm Random Distributed Feedback Fiber Laser
IEEE 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.

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.

Random distributed feedback fibre lasers
Physics Reports, 2014 The concept of random lasers making use of multiple scattering in amplifying disordered media to generate coherent light has attracted a great deal of attention in recent years. Here, we demonstrate a fibre laser with a mirrorless open cavity that operates via Rayleigh scattering, amplified through the Raman effect.

Time-delay signature suppression in a chaotic semiconductor laser by fiber random grating induced random distributed feedback [PDF]
Optics Letters, 2017 We demonstrate that a semiconductor laser perturbed by distributed feedback with random time delays from a large number of scattering centers along a fiber random grating can emit light chaotically without the time-delay signature (TDS).

Modeling of spectral and statistical properties of a random distributed feedback fiber laser
Optics Express, 2013 For the first time we report full numerical NLSE-based modeling of generation properties of random distributed feedback fiber laser based on Rayleigh scattering. The model which takes into account the random backscattering via its average strength only describes well power and spectral properties of random DFB fiber lasers.

Cascaded random distributed feedback Raman fiber laser operating at 12 μm
Optics Express, 2011 We demonstrate a CW random distributed feedback Raman fiber laser operating in a 1.2 μm spectral band. The laser generates up to 3.8 W of the quasi-CW radiation at 1175 nm with the narrow spectrum of 1 nm. Conversion efficiency reaches 60%. Up to 1 W is generated at the second Stokes wavelength of 1242 nm.

Multi-peak structure of generation spectrum of random distributed feedback fiber Raman lasers
Optics Express, 2017 We study spectral features of the generation of random distributed feedback fiber Raman laser arising from two-peak shape of the Raman gain spectral profile realized in the germanosilicate fibers.
