Broadband Coherent Raman Scattering Microscopy [PDF]

Laser and Photonics Reviews, 2018
AbstractSpontaneous Raman (SR) microscopy allows label‐free chemically specific imaging based on the vibrational response of molecules; however, due to the low Raman scattering cross section, it is intrinsically slow. Coherent Raman scattering (CRS) techniques, by coherently exciting vibrational oscillators in the focal volume, increase signal levels ...

Coherent anti-Stokes Raman Scattering Microscopy [PDF]

ChemPhysChem, 2007
AbstractCoherent anti‐Stokes Raman scattering (CARS) microscopy is presented as a new nonlinear optical technique. The combination of vibrational spectroscopy and microscopy allows highly sensitive investigations of unlabelled samples. CARS is an ideal tool for studying a broad variety of samples.

Pulse compression by coherent raman scattering

2007 Quantum Electronics and Laser Science Conference, 2007
The 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.

Simultaneous observation of rotational coherent Stokes Raman scattering and coherent anti-Stokes Raman scattering in air and nitrogen

Optics Letters, 1983
We report the first simultaneous observation to our knowledge of pure rotational coherent Stokes Raman scattering (CSRS) and coherent anti-Stokes Raman scattering (CARS) using broadband generation and detection. Three-dimensional small-angle phase-matching conditions for CSRS and CARS processes are discussed.

Coherent anti-Stokes Raman scattering in a microcavity

Optics Letters, 2009
We 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, 2010
AbstractIn 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, 1988
Abstract 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.
