The Role of Transiency in the Formation of Solitons in Stimulated Raman Scattering

Abstract

Recently there has been considerable interest in the formation of solitons in three level systems,1 such as in Raman scattering.2-5 Solitons in stimulated Raman scattering were first predicted by Chu and Scott,6 but their experimental realization seemed remote because of the apparent necessity for particular pulse shapes for the polarization and fields. It is now clear that solitons do indeed form7 in SRS and that transiency plays a major role in their formation.

Spontaneous solitons in stimulated Raman scattering

David C. MacPherson, R. C. Swanson, John L. Carlsten

It has been predicted that quantum fluctuations will lead to the formation of spontaneous solitons in stimulated Raman scattering. We present experimental data in support of this prediction. From an ensemble of 1000 shots we found solitonlike pulses in 101 shots. We have measured the distribution of soliton heights and delay times.

Stimulated Raman scattering (SRS) is one of the ideal systems which provide a macroscopic manifestation of quantum fluctuation associated with spontaneous noise.

Quantum initiation of stimulated Raman scattering

R. C. Swanson, David C. MacPherson, John L. Carlsten

In our studies of soliton formation in stimulated Raman scattering (SRS), we have discovered that a fully quantum mechanical theory predicts large shot-to-shot fluctuations in the SRS power spectrum, which leads to soliton decay. This theory, which includes a Langevin operator to simulate collision-induced fluctuations and maintain operator consistency, can be used to generate the statistics of the macroscopic SRS output. We have also studied a simpler model which uses a random vacuum field as an input to the semiclassical SRS equations. The vacuum field was numerically generated by summing a set of electromagnetic field modes that spanned the collisional Raman linewidth. Each mode was separated in frequency by less than the resolution of the system and given a random phase for each shot. Despite the lack of Langevin terms, the shot-to-shot variations and two-frequency correlation function from the simple approach were essentially indistinguishable from the fully quantum mechanical theory. This suggests that a simulation of SRS from spontaneous emission does not always require Langevin terms in the quantum noise.

Raman Solitons and Raman spikes

Jérôme J.-P. Leon, А. В. Михайлов

Stimulated Raman scattering of a laser pump pulse seeded by a Stokes pulse generically leaves a two-level medium initially at rest in an excited state constituted of static solitons and radiation. The soliton birth manifests as sudden very large variations of the phase of the output pump pulse. This is proved by building the IST solution of SRS on the semi-line, which shows moreover that initial Stokes phase flips induce Raman spikes in the pump output also for short pulse experiments.

Solitonlike Stokes pulses in near-resonance stimulated Raman scattering

Steven F. DiMarco, Michael E. Crenshaw, Cyrus D. Cantrell

This report demonstrates results of a numerical calculation in which the Maxwell-Bloch equations for near-resonance stimulated Raman scattering (SRS) are solved. We find that the Stokes field experiences parametric amplification and, because of pump field breakup into solitons, forms solitonlike structures.

Bright–bright 2π solitons in stimulated Raman scattering

A. E. Kaplan, P. L. Shkolnikov, B. A. Akanaev

We found conditions for excitation of bright-bright 2pi solitons in stimulated Raman scattering that involves nutation of population at Raman quantum levels, for two (laser-Stokes) and three (e.g., laser-Stokes-anti-Stokes) components. The soliton components at all participating frequencies are bright solitons of the same, Lorentzian, shape, in contrast to the well-known bright-dark soliton combination in stimulated Raman scattering.
