Coherent Raman scattering imaging with a near-infrared achromatic metalens [PDF]

open access: yesAPL Photonics, 2021
Miniature handheld imaging devices and endoscopes based on coherent Raman scattering are promising for label-free in vivo optical diagnosis. Toward the development of these small-scale systems, a challenge arises from the design and fabrication of ...

Coherent Raman Scattering Microscopy in Oncology Pharmacokinetic Research [PDF]

open access: yesFrontiers in Pharmacology, 2021
The high attrition rates of anti-cancer drugs during clinical development remains a bottleneck problem in pharmaceutical industry. This is partially due to the lack of quantitative, selective, and rapid readouts of anti-cancer drug activity in situ with ...

Coherent Stokes Raman scattering microscopy (CSRS)

open access: yesNature Communications, 2023
We report the first implementation of laser scanning coherent Stokes Raman scattering (CSRS) microscopy. To overcome the major challenge in CSRS imaging, we show how to suppress the fluorescence background by narrow bandpass filter and a lock-in based ...

The marriage of coherent Raman scattering imaging and advanced computational tools [PDF]

open access: yesLight: Science & Applications, 2023
Coherent Raman scattering microscopy can provide high-contrast tissue and single-cell images based on the inherent molecular vibrations of the sample. However, conventional techniques face a three-way trade-off between Raman spectral bandwidth, imaging ...

Noise auto-correlation spectroscopy with coherent Raman scattering [PDF]

open access: yesNature Physics, 2007
Ultrafast lasers have become one of the most powerful tools in coherent nonlinear optical spectroscopy. Short pulses enable direct observation of fast molecular dynamics, whereas broad spectral bandwidth offers ways of controlling nonlinear optical ...

Coherent Raman scattering with plasmonic antennas [PDF]

open access: yesNanophotonics, 2019
Coherent Raman scattering (CRS) techniques are recognized for their ability to induce and detect vibrational coherences in molecular samples. The generation of coherent light fields in CRS produces much stronger signals than what is common in incoherent ...

Coherent anti‐Stokes Raman Scattering Microscopy [PDF]

open access: yesChemPhysChem, 2007
AbstractCoherent anti‐Stokes Raman scattering (CARS) microscopy is presented as a new nonlinear optical technique. The combination of vibrational spectroscopy and microscopy allows highly sensitive investigations of unlabelled samples. CARS is an ideal tool for studying a broad variety of samples.

Comparison of coherent phonon generation by electronic and ionic Raman scattering in LaAlO_{3}

open access: yesPhysical Review Research, 2021
In ionic Raman scattering, infrared-active phonons mediate a scattering process that results in the creation or destruction of a Raman-active phonon. This mechanism relies on nonlinear interactions between phonons and has in recent years been associated ...

A Review of Raman-Based Technologies for Bacterial Identification and Antimicrobial Susceptibility Testing

open access: yesPhotonics, 2022
Antimicrobial resistance (AMR) is a global medical threat that seriously endangers human health. Rapid bacterial identification and antimicrobial susceptibility testing (AST) are key interventions to combat the spread and emergence of AMR.

The influence of phase-modulation on femtosecond time-resolved coherent Raman spectroscopy [PDF]

open access: yes, 1988
The influence of phase-modulation on femtosecond time-resolved coherent Raman scattering is investigated theoretically and experimentally. The coherent Raman signal taken as a function of the spectral position shows unexpected temporal oscillations close
