Amplifier/compressor fiber Raman lasers

Annual Meeting Optical Society of America, 1987
When pump and Stokes pulses copropagate in a fiber Raman laser (FRL), the weaker Stokes spectrum is severely broadened through pump-induced cross-phase modulation (XPM).1 Thus, in an FRL during Raman amplification, the pulse is chirped through XPM, and then the linear anomalous dispersion of a fiber can compress the pulse.

Distributed feedback fiber Raman laser

IEEE Journal of Quantum Electronics, 2001
We analyze the properties of a distributed feedback fiber laser based on Raman amplification. Such a laser is quite practical and has a number of novel properties. We model numerically the laser dynamics, analyze in detail the role of the nonlinear refractive index of the fiber and argue on the optimal design parameters.

Raman Fiber Laser Arrays

Conference on Lasers and Electro-Optics/International Quantum Electronics Conference, 2009
We propose and analyze coupled fiber lasers based on Raman gain. The nonlinear phases inherent in the stimulated Raman scattering process are shown to contribute to the phase locking mechanism in the weak coupling regime.

Fiber Raman lasers

Fiber and Integrated Optics, 1979
Optical fibers can exhibit wavelength conversion and other nonlinear optical effects at powers less than one watt. The reason has little to do with the glass in the fiber core, which is one of the least nonlinear of all materials, but rather with the tremendous interaction length possible in low-loss fibers.

Raman fiber laser-pumped 2-μm fiber laser

SPIE Proceedings, 2003
We have demonstrated a Tm-Ho-codoped silica fiber laser pumepd by a third-stokes Raman Fiber Laser (RFL) at 1212 nm. RFL consists of Yb-double clad fiber laser (DCFL) as a pump, 1-km Single mode fiber (SMF) and cascated cavities made with fiber Bragg gratings (FBG).

Spectral broadening in Raman fiber lasers

Optics Letters, 2006
We present an analytical theory based on wave kinetic equations that describes a Raman fiber laser (RFL) generation spectrum. It is shown both theoretically and experimentally that the quasi-degenerate four-wave mixing between different longitudinal modes is the main broadening mechanism in the one-stage RFL at high powers.

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.

Raman Fiber Lasers

2004
The use of stimulated Raman scattering (SRS) as a means of amplifying signals in telecommunication systems has been demonstrated since 1976 [1]. Yet despite its advantages over erbium-doped fiber, Raman amplification was not used in the first generation of deployed optically amplified systems.

Chalcogenide glass Raman fiber laser

Applied Physics Letters, 2006
We report the operation of a chalcogenide glass Raman fiber laser. To mitigate photoinduced effects and minimize impurity absorption, a 2051nm Tm3+-doped silica fiber laser was employed as the pump source. Vibrations between the polymerlike layers comprising the glass produced first Stokes emission at 2062nm, an output power of 0.64W, and a slope ...

Cascaded Raman Fiber Lasers

2017
High power fiber lasers have seen tremendous development in the last decade with output powers exceeding 10 kW from a single fiber. This development is fueled simultaneously by industrial and defense applications. This rapid advance in technology has occurred with rare-earth doped fiber lasers, specifically Ytterbium doped fiber lasers at the forefront.
