Broadband Coherent Raman Scattering: Excitation Architectures and Operating Regimes [PDF]

Molecules
Coherent Raman scattering (CRS) techniques such as coherent anti-Stokes Raman scattering (CARS) provide chemically specific vibrational contrast with signal levels far exceeding spontaneous Raman scattering (SpRS). Extending these to broadband excitation

Imaging the intact mouse cornea using coherent anti-stokes Raman scattering (CARS). [PDF]

Invest Ophthalmol Vis Sci, 2013
The aim of this study was to image the cellular and noncellular structures of the cornea and limbus in an intact mouse eye using the vibrational oscillation of the carbon-hydrogen bond in lipid membranes and autofluorescence as label-free contrast agents.Freshly enucleated mouse eyes were imaged using two nonlinear optical techniques: coherent anti ...

Coherent anti-stokes Raman scattering (CARS) microscopy: a novel technique for imaging the retina. [PDF]

Invest Ophthalmol Vis Sci, 2013
To image the cellular and noncellular structures of the retina in an intact mouse eye without the application of exogenous fluorescent labels using noninvasive, nondestructive techniques.Freshly enucleated mouse eyes were imaged using two nonlinear optical techniques: coherent anti-Stokes Raman scattering (CARS) and two-photon autofluorescence (TPAF ...

Heat evacuation from active Raman media using frequency-selective dissipative coupling

Physical Review Research, 2021
We propose to use frequency-selective dissipative coupling to reduce the heat generated by coherent anti-Stokes Raman scattering (CARS) reversed cycles in active Raman media with phase mismatch.

Femtosecond coherent anti-Stokes Raman scattering (fs-CARS) for temperature and concentration measurements on combustion species using a dual output OPCPA [PDF]

EPJ Web of Conferences, 2019
Using two beam femtosecond coherent anti-Stokes Raman scattering (fs-CARS), temperature and concentration measurements are performed on relevant combustion species such as H2, N2, CO, and CO2.

Planar Laser Induced Fluorescence of OH for Thermometry in a Flow Field Based on Two Temperature Point Calibration Method

Applied Sciences, 2022
In view of the uncertainty in the calibration process of two-color plane laser-induced fluorescence (PLIF) temperature measurement, a new calibration method is proposed, in which the influence of fluorescence yield is considered.

Influence of the Raman depolarisation ratio on far-field radiation patterns in coherent anti-Stokes Raman scattering (CARS) microscopy [PDF]

Journal of the European Optical Society-Rapid Publications, 2006
We propose a full-vectorial numerical study of far-field radiation patterns in coherent anti-Stokes Raman scattering (CARS) microscopy. We emphasis the particular role of the Raman depolarisation ratio of the observed medium and show how it modifies the ...
