Analytic ab initio calculations of coherent anti-Stokes Raman scattering (CARS)

Physical Chemistry Chemical Physics, 2009
We present a theory for the analytic calculation of frequency-dependent polarizability gradients, and apply the methodology to the calculation of coherent anti-Stokes Raman scattering (CARS). The formalism used is based on an open-ended theory for the calculation of frequency-dependent molecular response properties of arbitrary order, also including ...

USING COHERENT ANTI-STOKES RAMAN SCATTERING (CARS) TO IMAGE BRAIN TISSUES

2007 4th IEEE International Symposium on Biomedical Imaging: From Nano to Macro, 2007
We present our findings on using coherent anti-Stokes Raman scattering (CARS) microscopy to image brain tissue slices. Compared with other modalities such as confocal and two-photon laser scanning microscopy, CARS microscopy offers chemical selectivity with high sensitivity without the need for any labeling agents.

Interferometric polarization coherent anti-Stokes Raman scattering (IP-CARS) microscopy

Optics Letters, 2008
We report a novel interferometry-based polarization coherent anti-Stokes Raman scattering (IP-CARS) implementation for effectively suppressing the nonresonant background while significantly amplifying the resonant signal for vibrational imaging. By modulating the phase difference between the two interference CARS signals generated from the same sample ...

Vibrational imaging by coherent anti-stokes Raman scattering (CARS) microscopy

SPIE Proceedings, 2004
An approach for the chemical imaging of molecular systems is presented, based on coherent anti-Stokes Raman scattering microscopy/spectroscopy (CARS). This technique permits to map selectively molecular species, by using vibrational properties of their chemical bounds.

Coherent anti-Stokes Raman scattering microscopy (CARS): Instrumentation and applications

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2007
Abstract Recent advances in laser physics have permitted the development of a new kind of microscopy based on stimulated Raman scattering. This new technique known as Coherent anti-Stokes Raman scattering (CARS) microscopy allows vibrational imaging with high sensitivity, high spectral resolution and three-dimensional sectioning capabilities.

Coherent anti-Stokes Raman scattering (CARS) holographic biological imaging

CLEO:2011 - Laser Applications to Photonic Applications, 2011
We demonstrate non-scanning three-dimensional (3D) imaging of cellular components in live cancerous (HeLa) cells by combining the chemical selectivity of CARS with the 3D imaging capability of holography to establish a new technique for bio-imaging.

A practical analysis for coherent anti‐stokes Raman scattering (CARS) spectra

Journal of Raman Spectroscopy, 1979
AbstractIn coherent anti‐Stokes Raman scattering (CARS) spectra for condensed phases, the shape and position of an isolated line depend on the Raman cross‐section, the linewidth, the vibrational frequency and the nonresonant electronic susceptibility.

Highly efficient coherent anti-Stokes Raman scattering (CARS) microscopy

SPIE Proceedings, 2004
Coherent Anti-Stokes Raman Scattering (CARS)-microscopy has in recent years developed as a promising microscopical technique for label-free microscopy of living cells. We propose a new concept, spectral focusing, for highly efficient coherent anti-Stokes Raman scattering (CARS) microscopy.

Coherent anti-stokes raman scattering (cars) of large C2H4Ar clusters

Chemical Physics Letters, 1982
Abstract CARS spectra from a supersonic molecular beam of ethylene/argon mixtures show a strong signal close to the Q branch of the ν 2 vibration of ethylene. The pressure dependence and scaling laws for a condensing molecular beam indicate that it is due to large C 2 H 4 Ar clusters. The experiment did not permit the identification of the clusters.

Single pulse interferometric coherent anti-Stokes Raman scattering (CARS)

SPIE Proceedings, 2007
The non-resonant background signal has been the major obstacle in coherent anti-Stokes Raman scattering (CARS) spectroscopy and microscopy. This unwanted background is generated by the electronic response of the sample. It not only obscures the desired signal but also results in spectral interference with the desired vibrationally resonant CARS ...
