A label-free, fast and high-specificity technique for plant cell wall imaging and composition analysis

open access: yesPlant Methods, 2021
Background New cell wall imaging tools permit direct visualization of the molecular architecture of cell walls and provide detailed chemical information on wall polymers, which will aid efforts to use these polymers in multiple applications; however ...

Broadband Coherent Raman Scattering Microscopy [PDF]

open access: yesLaser & 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 ...

Multicolored Femtosecond Pulse Synthesis Using Coherent Raman Sidebands in a Reflection Scheme

open access: yesApplied Sciences, 2015
Broadband coherent Raman generation emerges as a successful method to produce multicolored femtosecond pulses and time-shaped laser fields. In our study, coherent Raman sidebands are generated in a Raman-active crystal, driven by two-color femtosecond ...

Coherent Raman Scattering Microscopy [PDF]

open access: yesJournal of Biomedical Optics, 2014
Reviewed by Alberto Diaspro, SPIE Fellow, Istituto Italiano di Tecnologia, Genova, Italy Research and development of modern optical microscopes are guided by several aspects, from resolution obsession to imaging of living specimens, from a low-level of perturbation to long-term experiments on biological systems.

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 ...

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

open access: yesAdvances 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 ...

Control of Raman Lasing in the Nonimpulsive Regime [PDF]

open access: yes, 2003
We explore coherent control of stimulated Raman scattering in the nonimpulsive regime. Optical pulse shaping of the coherent pump field leads to control over the stimulated Raman output.

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

open access: yesJournal 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.
