Novel Technique for Obtaining the Raman Gain Efficiency of Silica Fibers

open access: yesIEEE 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 ...

Amplification of Supercontinuum Seed Pulses at ~1078–1355 nm by Cascade Rotational SRS in Compressed Hydrogen

open access: yesApplied Sciences, 2023
Multiple higher-order Stokes of rotational stimulated Raman scattering (SRS) in compressed hydrogen covered the wavelength range from ~1.1 µm to ~1.4 µm using ~1.2 ps pump pulses from a Yb:YAG laser.

Frequency shifts in stimulated Raman scattering [PDF]

open access: yes, 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]

open access: yes, 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 ...

Lowering backward Raman and Brillouin scattering in waveguide Raman wavelength converters

open access: yesJournal 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

Photonic Time-Stretch Spectroscopy for Multiplex Stimulated Raman Scattering [PDF]

open access: yesEPJ 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 ...

Fiber Raman Amplifiers and Fiber Raman Lasers

open access: yesMicromachines, 2020
Stimulated Raman scattering (SRS) is a nonlinear optical effect, observed for the first time in 1962, which lies at the heart of fiber Raman amplifiers and fiber Raman lasers [...]

Tunable Stokes Laser Based on KTiOPO4 Crystal

open access: yesCrystals, 2020
The characteristics of a tunable Stokes laser based on the cascaded stimulated polariton scattering and stimulated Raman scattering in KTiOPO4 crystal were studied experimentally and theoretically.

Generation of frequency shifted picosecond pulses with low temporal jitter [PDF]

open access: yes, 1984
Transient stimulated Raman scattering is used for the generation of a frequency shifted picosecond light pulse; part of this Raman shifted pulse is subsequently coherently scattered at a material excitation of a second Raman cell.
