Nonlinear theory of transient stimulated Raman scattering and its application to long-pulse experiments

Nonlinear discrete systems with nonanalytic dispersion relations

“…In this case, the evolution of the spectral transform can be not only non homogeneous but also nonlinear and still has interesting physical application. In particular the problem of stimulated Raman scattering of a high energy long Laser pulse in a gas has been solved by this technique [27] [28].…”

Theory of Pump Depletion and Spike Formation in Stimulated Raman Scattering

“…The reason for this is that the input data are of finite duration and the interaction is local (for any fixed time). We show in [14] that indeed the generated material excitation is localized in a small region (of length comparable with the duration of the amplified Stokes pulse).…”

Observation of Solitary Waves with Different Phase Behavior in Stimulated Raman Forward Scattering

“…The phase jump can be deterministically generated [3,4], or originates from quantum-noise fluctuations of the Stokes wave and the medium at the beginning of the scattering process [5][6][7]. The phase behavior of the Stokes wave and the mutual phase relations between the pump and Stokes fields and medium polarization have been thoroughly investigated by a number of authors [8][9][10][11][12][13]. However, to the best of our knowledge, the question of whether the phase of the solitary wave occurring in the depleted pump has only one form of appearance at its disposal or perhaps more has not received very much attention so far [1].…”
