چکیده
In this work, we experimentally investigate several temporal and spectral methods to highlight extreme fluctuations which can develop during the Raman amplification of an ultrashort pulse train. Forward and backward pumping schemes are compared to dual pass configurations.

Extreme optical fluctuations in lumped Raman fibre amplifiers
A numerical study about the generation of extreme events in lumped Raman fibre amplifier is performed. Evolutions of continuous or pulsed signals are analysed using crosscorrelations, spectra and probability density functions. For pulsed signals, the phase evolution is also explored. Both signal and Stokes cascaded waves are considered.
متن کاملExtreme statistics in Raman fiber amplifiers : influence of pump depletion and dispersion
We experimentally and theoretically investigate the influence of pump depletion effects on extreme statistics observed in fiber Raman amplifiers. We also report on the impact of the dispersion of the fiber. OCIS codes: (060.4370) Nonlinear optics, fibers; (060.2320) Fiber optics amplifiers.
متن کاملImpact of Fourth-Order Dispersion Coefficient on the Gain Spectrum and the Saturation Behavior of One-Pump Fiber Optical Parametric Amplifiers
In this paper, the gain spectrum and the saturation behavior of one-pump fiber optical parametric amplifiers (1-P FOPAs) are investigated by taking into account the fourth-order dispersion coefficient b4 in the analysis. The results show that it is necessary to consider b4 in the analysis when the wavelength difference between the signal and pump waves is large enough and/or whenever the pump w...
متن کاملVector theory of stimulated Raman scattering and its application to fiber-based Raman amplifiers
A vector theory of the stimulated Raman scattering process is developed for describing the polarization effects in fiber-based Raman amplifiers. We use this theory to show that polarization-mode dispersion (PMD) induces large fluctuations in an amplified signal. It is found that PMD-induced fluctuations follow a log-normal distribution. We also discuss the random nature of the polarization-depe...
متن کاملExtreme value statistics in quasi-CW Raman fiber lasers
It is found that rare extreme events are generated in a Raman fiber laser. The mechanism of the extreme events generation is a turbulent-like four-wave mixing of numerous longitudinal generation modes. OCIS codes: (190.4370) Nonlinear optics, fibers; (190.4380) Nonlinear optics, four-wave mixing Extreme type statistics in nonlinear fiber optics has attracted a great attention since the experime...
