Novel Technique for Obtaining the Raman Gain Efficiency of Silica Fibers
IEEE Photonics Journal, 2013 We present a simple novel technique that determines with precision the Raman gain efficiency for telecom fibers. The method is supported by a mathematical relation, which is the solution for the coupled differential equations that govern the stimulated ...

Frequency shifts in stimulated Raman scattering [PDF]
, 1980 The nonresonant contributions to the nonlinear susceptibility χ(3) produce a frequency chirp during stimulated Raman scattering. In the case of transient stimulated Raman scattering, the spectrum of the generated Stokes pulse is found at higher ...

Raman gain against a background of non-thermal ion fluctuations in a plasma [PDF]
, 2000 A complex stimulated Raman scattering event against a background of non-thermal ion acoustic waves in an inhomogeneous plasma is described. We obtain analytic forms for the Raman gain due to a five-wave interaction consisting of conventional three-wave ...

Photonic Time-Stretch Spectroscopy for Multiplex Stimulated Raman Scattering [PDF]
EPJ Web of Conferences, 2019 Stimulated Raman scattering spectroscopy enables label-free molecular identification, but its broadband implementation is technically challenging. We experimentally demonstrate a novel approach to multiplex stimulated Raman scattering based on photonic ...

Lowering backward Raman and Brillouin scattering in waveguide Raman wavelength converters
Journal of the European Optical Society-Rapid Publications, 2017 Background Liquid filled hollow core fiber Raman wavelength converters are devices enabling to red-shift the wavelength of laser beams delivered by either fixed wavelength or tunable lasers. Most of the reported converters operate in a pulsed regime with

Control of Raman Lasing in the Nonimpulsive Regime [PDF]
, 2003 We explore coherent control of stimulated Raman scattering in the nonimpulsive regime. Optical pulse shaping of the coherent pump field leads to control over the stimulated Raman output.
