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.

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 ...

Optimisation of wavelength modulated Raman spectroscopy : towards high throughput cell screening [PDF]

open access: yes, 2013
In the field of biomedicine, Raman spectroscopy is a powerful technique to discriminate between normal and cancerous cells. However the strong background signal from the sample and the instrumentation affects the efficiency of this discrimination ...

Chirped pulse Raman amplification in plasma: high gain measurements [PDF]

open access: yes, 2009
High power short pulse lasers are usually based on chirped pulse amplification (CPA), where a frequency chirped and temporarily stretched ``seed'' pulse is amplified by a broad-bandwidth solid state medium, which is usually pumped by a monochromatic ...

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 ...

Contrast in coherent Raman scattering microscopy [PDF]

open access: yes, 2014
Coherent anti-Stokes Raman scattering (CARS) microscopy is becoming a widely used technique for sub-micron, chemically-selective imaging at high rates of speed In this thesis I discuss three methods for increasing the specificity and selectivity of coherent Raman experiments.

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.

Imaging intra-cellular wear debris with coherent anti-Stokes Raman scattering spectroscopy [PDF]

open access: yes, 2013
Aseptic loosening of artificial joints is caused by an osteolytic reaction to wear debris mediated by macrophages and other cells. Imaging these wear particles within cells can be a key process in understanding particle-cell interactions. However, the

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.
