Planar Laser Induced Fluorescence of OH for Thermometry in a Flow Field Based on Two Temperature Point Calibration Method

open access: yesApplied 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.

Influence of the Raman depolarisation ratio on far-field radiation patterns in coherent anti-Stokes Raman scattering (CARS) microscopy [PDF]

open access: yesJournal 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 ...

3D-coherent anti-Stokes Raman scattering Fourier ptychography tomography (CARS-FPT)

open access: yesOptics Express, 2021
Fourier ptychography tomography (FPT) is a novel computational technique for coherent imaging in which the sample is numerically reconstructed from images acquired under various illumination directions. FPT is able to provide three-dimensional (3D) reconstructions of the complex sample permittivity with an increased resolution compared to standard ...

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

open access: yesNanophotonics, 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.

Background-free time-resolved coherent Raman spectroscopy (CSRS and CARS): Heterodyne detection of low-energy vibrations and identification of excited-state contributions

open access: yesAPL Photonics, 2019
Coherent Raman scattering (CRS) spectroscopy techniques have been widely developed and optimized for different applications in biomedicine and fundamental science. The most utilized CRS technique has been coherent anti-Stokes Raman scattering (CARS), and

Coherent anti-Stokes Raman spectroscopy of single and multi-layer graphene

open access: yesNature Communications, 2019
Coherent anti-Stokes Raman Scattering (CARS) accesses the vibrational properties of a material via nonlinear four-wave mixing (FWM); CARS in graphene has not been observed to date despite its high nonlinear third-order susceptibility.

High-resolution imaging of graphene by tip-enhanced coherent anti-Stokes Raman scattering [PDF]

open access: yesJournal of Innovative Optical Health Sciences, 2019
Coherent anti-Stokes Raman scattering (CARS) is able to enhance molecular signals by vibrational coherence compared to weak Raman signal. The surface or tip enhancement are successful technologies, which make it possible for Raman to detect single ...

Non-linear label-free imaging through a multimode graded index optical fibre [PDF]

open access: yesEPJ Web of Conferences, 2020
In recent years, great advances have been made in developing minimal footprint micro-endoscopes using multimode optical fibres (MMF) [1]. By employing wavefront shaping methods the seemingly random speckle pattern resulting from the guiding of coherent ...
