Raman Fiber Lasers and Amplifiers

Frontiers in Optics 2015, 2015
Raman gain is optically-pumped optical amplification. We discuss the discovery of the Raman effect and Raman amplification. Relevant fiber properties are introduced along with an overview of different approaches to Raman amplification. Applications as lasers and lightwave system amplifiers are shown.

Cascade Raman soliton fiber ring laser

Optics Letters, 1987
Pulses as short as 200 fsec at 1.5 microm and 230 fsec at 1.6 microm have been generated through a cascade Raman, solitonlike process in a fiber ring oscillator. A dispersion-shifted (lambda(0) = 1.46 microm) single-mode fiber was used as the gain medium, which was synchronously pumped by a cw mode-locked Nd:YAG laser operated at 1.32 microm.

Dynamical model of Raman fiber lasers

SPIE Proceedings, 2014
Numerical model of fiber laser is proposed suitable for numerical investigation of fiber laser dynamics. The model is based on the equations describing propagation effects, linear coupling of oppositely running pulses and its interaction in a ring or standing-wave fiber cavity.

Raman fiber lasers for optical communication application

Annales Des Télécommunications, 2003
We review the principle and characteristics of cascaded Raman fiber lasers in their telecommunication applications. The fundamentals of Raman fiber lasers are described, such as pumping scheme, fiber type and reflectors. We explain simple equations forcw laser operation as well as a possible way to calculate spectral width.

Spectral modeling of Raman fiber lasers

IEEE Photonics Technology Letters, 2003
This letter describes a model of Raman fiber lasers, based on the four-wave mixing interaction between the laser modes. The results predict the laser spectral shape and output power with good accuracy.

Specialty Optical Fibers for Raman Lasers

2017
As described in the preceding chapters, the performances of Raman fiber lasers and amplifiers are governed by the parameters (including Raman gain coefficients, Raman shift, transmission window and loss, damage threshold, chemical and thermal stability, etc.) of optical fibers.
