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 ...

Background free CARS imaging by phase sensitive heterodyne CARS [PDF]

open access: yes, 2008
In this article we show that heterodyne CARS, based on a controlled and stable phase-preserving chain, can be used to measure amplitude and phase information of molecular vibration modes.

Wide-field coherent anti-Stokes Raman scattering microscopy based on picosecond supercontinuum source

open access: yesAPL Photonics, 2018
We present a wide-field coherent anti-Stokes Raman scattering microscopy setup based on picosecond-laser-pumped supercontinuum and use it to demonstrate video-rate imaging with chemical specificity. The broadband excitation allows simultaneous imaging of

Three-pulse multiplex coherent anti-Stokes/Stokes Raman scattering (CARS/CSRS) microspectroscopy using a white-light laser source [PDF]

open access: yes, 2013
We have developed a three-pulse non-degenerate multiplex coherent Raman microspectroscopic system using a white-light laser source. The fundamental output (1064 nm) of a Nd:YAG laser is used for the pump radiation with the white-light laser output (1100 ...

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.

Compressive coherent anti-Stokes Raman scattering holography

open access: yesOptics Express, 2015
Coherent anti-Stokes Raman scattering (CARS) holography captures both the amplitude and the phase of the anti-Stokes field generated from a sample and can thus perform single-shot, chemically selective three-dimensional imaging. We present compressive CARS holography, a numerical technique based on the concept of compressive sensing, to improve the ...

Interferometric Fourier transform Coherent anti-Stokes Raman Scattering

open access: yesOptics Express, 2006
We present an interferometric time-domain Fourier transform implementation of coherent anti-Stokes Raman scattering (CARS). Based on a single femtosecond laser source, the method provides a straight-forward scheme for obtaining high resolution CARS spectra.
