Coherent Stokes Raman Scattering for Simultaneous Measurement of CO2 and CH4 Temperatures

Journal of Raman Spectroscopy, Volume 57, Issue 10, Page 1644-1653, October 2026.
A three‐beam hybrid fs/ps CSRS method is employed to excite the rovibrational transitions in the Fermi‐dyad of CO 2 and the v2 mode of CH 4. Time‐domain spectroscopic models are developed to extract the fuel and flame temperature profiles from experimental CH 4 and CO 2 spectra in a diffusion flame.

Optical Nano-Imaging of Materials: Peeping Through Tip-Enhanced Raman Scattering

CHIMIA, 2006
High-resolution optical nano-imaging, with a spatial resolution far beyond the diffraction limits of the probing light, has been shown by means of tip-enhanced near-field Raman spectroscopy.

Nonlinear optical microscopies (NOMs) and plasmon-enhanced NOMs for biology and 2D materials

Nanophotonics, 2020
In this review, we focus on the summary of nonlinear optical microscopies (NOMs), which are stimulated Raman scattering (SRS), coherent anti-Stokes Raman scattering (CARS), second harmonic generation (SHG), and two-photon excited fluorescence (TPEF). The

Fourier-transform coherent anti-Stokes Raman scattering microscopy [PDF]

Optics Letters, 2006
We report a novel Fourier-transform-based implementation of coherent anti-Stokes Raman scattering (CARS) microscopy. The method employs a single femtosecond laser source and a Michelson interferometer to create two pulse replicas that are fed into a scanning multiphoton microscope.

Label‐Free Myelin Fingerprinting: An Adult Human Post‐Mortem Brain Slice Platform via Coherent Anti‐Stokes Raman Spectroscopy

Advanced Science, Volume 13, Issue 54, 28 September 2026.
A serum‐free, air–liquid interface organotypic slice culture model preserves human post‐mortem corpus callosum tissue, successfully recovering from slicing trauma to reflect the donor's underlying disease state. Pairing label‐free Coherent anti‐Stokes Raman scattering (CARS) microscopy with k‐means clustering enables objective, high‐resolution ...

Phase‐shaping strategies for coherent anti‐Stokes Raman scattering

Journal of Raman Spectroscopy, 2011
AbstractThe identification of large molecules in complex environments requires probing of multiple vibrational resonances rather than a single resonance. Phase‐shaping the excitation pulses allows the coherent mixing of several resonances so that the presence of molecules can be inferred directly from the integrated output pulse energy. This avoids the

Thin‐film lithium niobate photonics: Frontiers in millimeter‐wave and terahertz generation and integrated applications

InfoScience, Volume 3, Issue 3, September 2026.
With the advancement of 6G communications, high‐precision radar, and advanced imaging technologies, there is a growing demand for compact, high‐performance light sources capable of generating high‐frequency radio waves (millimeter‐wave and terahertz waves). This article systematically introduces how to efficiently generate these high‐frequency waves on

Advances in Femtosecond Coherent Anti-Stokes Raman Scattering for Thermometry

Photonics
The combustion process is complex and harsh, and the supersonic combustion flow field is also characterized by short duration and supersonic speed, which makes the real-time diagnostic technology for the transient environment extremely demanding.
