TLDR
In this three-cascaded cw Raman laser, based on a single active phosphorus-doped silica fiber, for the first time to the authors' knowledge successive generation of Stokes components of essentially different frequency shifts has been realized.Abstract:
We report a laser-diode-pumped 1407-nm Raman fiber laser with an output power of 1 W. In this three-cascaded cw Raman laser, based on a single active phosphorus-doped silica fiber, for the first time to the authors’ knowledge successive generation of Stokes components of essentially different frequency shifts (1330 and 490 cm-1) has been realized. These Stokes components are associated with both constituents (P2O5 and SiO2) of the fiber core glass.read more

Four-wave-mixing-induced turbulent spectral broadening in a long Raman fiber laser
TL;DR: In this article, the authors present a self-consistent theory based on wave kinetic equations that describes the generation spectrum and output power of a Raman fiber laser (RFL), and show that the quasi-degenerate four-wave mixing between different longitudinal modes is the main broadening mechanism in the one-stage RFL at high powers.

Optical absorption characteristics of hydroxyl radicals in phosphorus-containing silica glass
TL;DR: In this paper, the optical absorption of hydroxyl radicals in phosphorus-containing silica glass was measured both for fundamental and harmonic absorptions, and it was shown that a larger part of the OH radicals are permanently trapped at phosphorus sites and are eliminated from contributing to optical losses in communication-type optical fibres.
