Concentration dependence in coherent Raman scattering
Journal of Modern Optics, 2008We investigate the concentration dependence of the femtosecond coherent anti-stokes Raman scattering (CARS) signals collected from several mixtures of molecules. We demonstrate a clear quadratic dependence of the transmitted CARS signal on the number of molecules of pyridine in water by looking at the Raman signal at 1030 cm−1.

Pulse compression by coherent raman scattering
2007 Quantum Electronics and Laser Science Conference, 2007The width of an ultraviolet pulse is compressed to sub-20 fs from 100 fs using a prism compressor by compensating the group delay dispersion among the Raman sidebands generated by coherent Raman scattering.

Coherent anti-Stokes Raman scattering in a microcavity
Optics Letters, 2009We study tight focus coherent anti-Stokes Raman scattering (CARS) emission in a microcavity where the active medium is squeezed between two independent planar mirrors. We show strong modifications in the CARS forward and backward far-field radiation patterns. For low-order cavities, we demonstrate that most of the emitted power can be concentrated into

Coherent anti‐Stokes Raman scattering in Raman lasers and Raman wavelength converters
Laser & Photonics Reviews, 2010AbstractIn this paper recent research progress on the use of Coherent Anti‐Stokes Raman Scattering (CARS) in Raman lasers and Raman wavelength converters is reviewed. The latest insights in the physical nature and behavior of CARS are addressed, and the recent performance breakthroughs in CARS‐based Raman wavelength conversion are discussed.

The “coherence peak” in time-resolved coherent Raman scattering
Optics Communications, 1988Abstract A signal overshoot (“coherence peak”) is predicted for coherent Raman scattering, if the excitation pulses and the probe pulse overlap in time. We discuss the conditions in detail, under which this phenomenon occurs. Experimental results are reported for benzene and liquid nitrogen which agree well with our theoretical expectations.

Second-order coherent Raman scattering
Physical Review A, 1978Detailed dispersion curves of second-order coherent anti-Stokes Raman scattering (CARS) (${\ensuremath{\omega}}_{4}=3{\ensuremath{\omega}}_{1}\ensuremath{-}2{\ensuremath{\omega}}_{2}$) are reported for benzene with the laser frequency difference ${\ensuremath{\omega}}_{1}\ensuremath{-}{\ensuremath{\omega}}_{2}$ near the 992-${\mathrm{cm}}^{\ensuremath{-

On the spectra of resonant coherent Raman scattering
Optical and Quantum Electronics, 1980The spectra of resonant coherent anti-Stokes and Stokes Raman scattering of excited molecules are calculated and discussed. The interaction of light and molecules is treated semi-classically. The energy level diagram of four energy levels describing the process is used in four modifications possible for excited molecules.

Fröhlich coherent vibrations and raman scattering
Czechoslovak Journal of Physics, 1991Coherent vibration systems are very likely composed of oscillating protein molecules located in the closed surface of the plasma membrane. Except short periods in the cell life, the distribution of the oscillating molecules corresponds to the condition of the minimum energy of the generated electromagnetic field.

Coherent Raman Scattering Microscopy
2009A series of advances over the past decade have made the combination of coherent Raman scattering (CRS) with optical microscopy a highly sensitive and chemically selective tool for the label-free and noninvasive analysis of chemical species or biological components inside a sub-femtoliter probe volume. By exploiting the coherent driving and detection of

Raman scattering of light by coherent polaritons
Soviet Journal of Quantum Electronics, 1975A theory is presented of the active speetroscopy using steady-state spontaneous Raman scattering by polaritons, i.e., spontaneous Raman scattering of a "test" wave ωπ by polaritons generated in an independent process of polariton stimulated Raman scattering of a given high-power pump wave ω1 with a possible additional illumination at the frequencies of
