Abstract The gain of stimulated Raman scattering (SRS) is based on the fact that the photon degeneracy of the pump beam (n¯p) and that of the scattering beam (n¯s) can be both >> 1, and therefore the latter can be increased exponentially. The SRS can be generated in both forward and backward directions.

Stimulated Raman scattering in nanostructured materials
2015 IEEE 15th International Conference on Nanotechnology (IEEE-NANO), 2015Nonlinear optics at nanoscale is an intriguing research field of great significance from both fundamental and applicative point of view. In this paper, the phenomena of stimulated Raman scattering in both nanostructured silica based materials and nanostructured silicon based materials are investigated and discussed.

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 ∞ =

Continuous-wave stimulated Raman scattering
Optics Letters, 1991We report what is to our knowledge the first observation of continuous-wave stimulated Raman scattering (SRS). Both forward and enhanced backward SRS were observed in liquids, and the large spectral frequency shift between pump and probe makes signal detection easy.

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 ...

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.

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.

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.
