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.

Spatial localization of hotspots in Fano-resonant plasmonic oligomers for surface-enhanced coherent anti-Stokes Raman scattering

Journal of the European Optical Society-Rapid Publications, 2020
Realization of Fano resonance in plasmonic oligomers is often exploited to design efficient plasmonic substrates for surface-enhanced coherent anti-Stokes Raman scattering.

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 ...

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.

Background signals in stimulated Raman scattering microscopy and current solutions to avoid them

Advances in Physics: X, 2023
Stimulated Raman scattering (SRS) microscopy has gained popularity in recent years due to its linearity to molecule concentration and laser intensity, and to the lack of the nonresonant background that affects its analogous technique, coherent anti ...

Polarimetric coherent anti-Stokes Raman scattering microscopy of collagen. [PDF]

Opt Lett
We demonstrate polarimetric coherent anti-Stokes Raman scattering (PCARS) microscopy for quantitative analysis of collagen orientation. Using polarization-modulated excitation and cross-polarized detection, we extract both chemical and orientational information from intact tissues.

Programmable hyperspectral coherent anti-Stokes Raman scattering microscopy. [PDF]

Opt Lett
Hyperspectral 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 ...

Wide-field coherent anti-Stokes Raman scattering microscopy based on picosecond supercontinuum source

APL Photonics, 2018
We present a wide-field coherent anti-Stokes Raman scattering microscopy setup based on picosecond-laser-pumped supercontinuum and use it to demonstrate video-rate imaging with chemical specificity. The broadband excitation allows simultaneous imaging of

Surface-enhanced FAST CARS: en route to quantum nano-biophotonics

Nanophotonics, 2018
Quantum nano-biophotonics as the science of nanoscale light-matter interactions in biological systems requires developing new spectroscopic tools for addressing the challenges of detecting and disentangling weak congested optical signals.
