Triple‐Resonance Coherent Anti‐Stokes Raman Scattering Microspectroscopy
ChemPhysChem, 2009AbstractFluorescence‐free microscopy: A new nonlinear optical microspectroscopy technique, femtosecond (fs) triple‐resonance coherent anti‐Stokes Raman scattering, in which the amplitude and phase of input fs laser pulses are optimally shaped to be in triple resonance with the molecular electronic and vibrational transitions, generates a coherent ...

COHERENT ANTI-STOKES RAMAN SCATTERING HOLOGRAPHY: THEORY AND EXPERIMENT
Journal of Nonlinear Optical Physics & Materials, 2012We review coherent anti-Stokes Raman scattering (CARS) holography as a non-scanning, label-free, three-dimensional imaging technique. The theory of CARS and its integration with digital holography is explored. We then discuss the experimental implementations of CARS holography including in-line and off-axis modalities and the demonstrations of three ...

Circularly polarized coherent anti-Stokes Raman scattering microscopy
Optics Letters, 2013We demonstrate circularly polarized coherent anti-Stokes Raman scattering (CP-CARS) microscopy that significantly suppresses the nonresonant background for high-contrast vibrational imaging. Circularly polarized pump and Stokes fields with opposite handedness are used to excite CARS signal.

Coherent anti-Stokes Raman scattering from small volumes
Optics Letters, 1984We have used coherent anti-Stokes Raman scattering spectroscopy to resolve the Raman Q-branch line [Q (2) at 2987.18 cm(-1)] of dueterium gas contained in a 60-microm-diameter glass sphere. The 60-microm spheres contained only 10(+13) molecules at standard temperature and pressure; this made it possible to study gases that in larger quantities would be

Programmable hyperspectral coherent anti-Stokes Raman scattering microscopy
Optics LettersHyperspectral coherent Raman scattering microscopy provides a significant improvement in acquisition time compared to spontaneous Raman scattering yet still suffers from the time required to sweep through individual wavenumbers. To address this, we present the use of a pulse shaper with a 2D spatial light modulator for phase- and amplitude-based ...

Coherent Anti-Stokes Raman Scattering of Gases
1982The first measurements involving Coherent Anti-Stokes Raman Scattering (CARS) in gases were by Rado (1967) [1], who determined the nonresonant susceptibilities of a number of gases by using a ruby laser and a H2 Stokes beam stimulated in a high pressure hydrogen cell.
