Stimulated Raman scattering in nanostructured materials

2015 IEEE 15th International Conference on Nanotechnology (IEEE-NANO), 2015
Nonlinear 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.

Stimulated Raman Scattering Microscopy in Single Cell

18th Italian National Conference on Photonic Technologies (Fotonica 2016), 2016
Taking 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.

Self-similarity in transient stimulated Raman scattering

Physical Review Letters, 1992
Stimulated 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.

The buildup of stimulated Raman scattering from spontaneous Raman scattering

Optics Communications, 1981
Abstract 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 ...

Three-beam double stimulated Raman scatterings

The Journal of Chemical Physics, 2018
Two-beam stimulated Raman scattering with pump and Stokes beams is manifest in both the Raman loss of the pump beam and the Raman gain of the Stokes beam, and it has been used in various label-free bioimaging applications. Here, a three-beam stimulated Raman scattering that involves pump, Stokes, and depletion beams is considered, where two stimulated ...

Chaos in stimulated Raman scattering

Czechoslovak Journal of Physics, 1992
Coherent state technique and maximal Lyapunov exponent method are used for the study of deterministic chaos in a system governing stimulated Raman scattering. The influence of the external pumping on dynamics of the system is investigated. Phase portraits and FFT spectra are presented.

Stimulated Raman scattering pulses. I. Weak scattering

Journal of Applied Spectroscopy, 1967
Rate equations are used to compute a weak stimulated Raman scattering pulse in the case where the scattered radiation energy can be neglected in the over-all energy balance. Expressions for the shape, position and height of the maximum, duration, and spectral width of the scattering pulse as functions of the parameters of the driving laser, scattering ...

Stimulated Raman scattering in quartz

IEEE Journal of Quantum Electronics, 1967
Stimulated Raman scattering (SRS) from infrared-active phonons in quartz is discussed. The scattering is concluded to be from a different region of k space than that previously stated in the literature. The possibility of producing a broadly tunable parametric oscillator via SRS in quartz is viewed with pessimism.
