Reassessment of the theory of stimulated Raman scattering
Physical Review B, 1985A modification of the standard theory of stimulated Raman scattering (SRS) first proposed by Sparks (1974, 1975) is analyzed and shown to incorporate a possibly important physical effect; however, its original formulation is incorrect. The analysis is based on an exact numerical integration of the coupled equations of the modified theory, the results ...

Transient solitons in stimulated Raman scattering
Annual Meeting Optical Society of America, 1988The normalized equations describing transient stimulated Raman scattering are1,2where A1and A2represent the pump and Stokes waves, Xis the material excitation, ϵis its damping rate, and χ and τare normalized distance and time. One readily finds that K(τ)=|A1(χ, τ)|2+ |A2(χ, τ)|2is constant for all χ. If, in addition, I ∞ =

This chapter describes the application of stimulated Raman scattering as a practical method for the generation of tunable, coherent radiation. A brief theoretical discussion of the stimulated Raman effect in the steady state and transient-scattering regimes is presented.

Stimulated Raman scattering in the presence of stimulated Brillouin scattering
The Physics of Fluids, 1988Particle simulations of stimulated Raman scattering (SRS) are presented in which stimulated Brillouin scattering (SBS) also occurs. Frequency spectra of forward and backscattered light are compared for various ratios of ion mass to electron mass. SBS is seen to weaken the SRS backscattering in all cases in which the plasma density profile includes the ...

Inelastic light scattering has proved to be highly valuable for the study of elementary excitations of gases, liquids and solids. The parameters of the scattered radiation, e.g. frequency position, spectral band shape, degree of polarization and scattering efficiency provide detailed information on the material under consideration.

The buildup of stimulated Raman scattering from spontaneous Raman scattering
Optics Communications, 1981Abstract We present a quantum electrodynamic theory which shows for the first time how stimulated Raman scattering builds up, both spatially and temporally, from spontaneous Raman scattering. We analytically solve operator Maxwell-Bloch equations to find the Stokes field operator, and thus the Stokes intensity, for both monochromatic and broad-band ...

Stimulated Raman Scattering Microscopy in Single Cell
18th Italian National Conference on Photonic Technologies (Fotonica 2016), 2016Taking advantage of vibrational contrast, a label-free imaging useful for single cell investigation, can be obtained by stimulated Raman scattering. In this work, the successful realisation of a nonlinear microscope, not available commercially, based on stimulated Raman scattering is described.

Exact solutions of the stimulated-Raman-scattering equations
Physical Review A, 1991Exact analytic solutions of the stimulated-Raman-scattering equations are obtained using group-theoretical methods. Special attention is devoted to a self-similar solution in terms of the fifth Painlevé transcendent 𝑃ᵥ. Its asymptotic behavior is established and shown to agree with experimental data and with earlier numerical calculations.

Self-similarity in transient stimulated Raman scattering
Physical Review Letters, 1992Stimulated Raman scattering in the transient limit is an integrable system. In contrast, however, to the usual behavior in integrable systems, solitons are transient and the behavior of the system at long distances is dominated by self-similar solutions which may be found by symmetry reduction.
