Statistics of Raman-Active Excitations via Masurement of Stokes-Anti-Stokes Correlations [PDF]

open access: yes, 1999
A general fundamental relation connecting the correlation of Stokes and anti-Stokes modes to the quantum statistical behavior of vibration and pump modes in Raman-active materials is derived.

BCARS Simulated Phantom Dataset for Evaluation of Processing Pipelines

open access: yesJournal of Raman Spectroscopy, EarlyView.
A tissue phantom, containing fingerprint Raman spectra at each pixel, is developed to evaluate Raman signal processing pipelines. The phantom is created from a BCARS image of a murine hepatic tissue. ABSTRACT Broadband coherent anti‐Stokes Raman scattering (BCARS) microscopy is a powerful label‐free biological imaging technique, but the raw signal ...

Spatially dependent Rabi oscillations: an approach to sub-diffraction-limited CARS microscopy [PDF]

open access: yes, 2009
We present a theoretical investigation of coherent anti-Stokes Raman scattering (CARS) that is modulated by periodically depleting the ground state population through Rabi oscillations driven by an additional control laser.

Temperature‐Dependent Investigation of the S‐Branch Raman Linewidth in CO2 via Time‐Resolved Rotational CARS

open access: yesJournal of Raman Spectroscopy, EarlyView.
We studied the temporal evolution of the rotational coherent anti‐Stokes Raman scattering (RCARS) signal of CO2 to determine the S‐branch Raman linewidth, which is an essential parameter for accurate spectral modeling in RCARS gas‐phase diagnostics. We found a non‐monotonic J‐dependence of the S‐branch Raman linewidth not accounted for in previously ...

Advances in Femtosecond Coherent Anti-Stokes Raman Scattering for Thermometry

open access: yesPhotonics
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.

Analytical capabilities of coherent anti-Stokes Raman scattering microspectroscopy [PDF]

open access: yesJournal of Modern Optics, 2008
Nonlinear Raman scattering is an emerging spectroscopy technique for non-invasive microscopic imaging. It can produce a fluorescence background free vibrational spectrum from a microscopic volume of a sample providing chemically specific information about its molecular composition.

Automated Imaging of Cultured Bacteria in Picoliter Droplets by Coherent Anti‐Stokes Raman Scattering and Two‐Photon Excited Fluorescence Microscopy

open access: yesJournal of Raman Spectroscopy, EarlyView.
We present an automated system that combines an image‐based fuzzy logic controller for precise positioning of microfluidic picoliter droplets with nonlinear microscopy, using CARS and TPEF modalities for detailed analysis of droplet composition. Time series and z‐stack images of E. coli, B. subtilis, and M. arborescens were recorded.

The contribution of vibrational spectroscopy and data analytics towards the achievement of the global sustainability goals

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract The United Nations Sustainable Development Goals (UN SDGs) were defined to improve the quality of life of the global population particularly regarding social and economic aspects, with a major focus on environmental sustainability. The incorporation of digital technologies into the agri‐food sector has become a key enabler in increasing the ...
