Raman Imaging of Nanocarriers for Drug Delivery

Nanomaterials, 2019
The efficacy of pharmaceutical agents can be greatly improved through nanocarrier delivery. Encapsulation of pharmaceutical agents into a nanocarrier can enhance their bioavailability and biocompatibility, whilst also facilitating targeted drug delivery ...

Two types of cooperation between the photons in multiple scattering lasing and their possible application

Physics Open
The two types of cooperative effects between the converted photons in the multiple steps of Raman lasing are proposed. The first type involves the cooperative process between the photons of one of the steps of Raman conversion.

Hyperspectral coherent anti-stokes Raman scattering (CARS) imaging

, 2020
Optische Analysen mikroskopischer Proben blicken auf eine lange Historie zurück, in der viele verschiedene Mikroskopietechniken über die Jahre hinweg entwickelt würden. Viele der optischen Mikroskopie-Methoden ermöglichen eine zerstörungsfreie und nicht-invasive Untersuchung der Proben.

Polarimetric coherent anti-Stokes Raman scattering microscopy of collagen

Optics Letters
We demonstrate polarimetric coherent anti-Stokes Raman scattering (PCARS) microscopy for quantitative analysis of collagen orientation. Using polarization-modulated excitation and cross-polarized detection, we extract both chemical and orientational information from intact tissues.

Coherent anti-Stokes Raman scattering in a microcavity

Optics Letters, 2009
We study tight focus coherent anti-Stokes Raman scattering (CARS) emission in a microcavity where the active medium is squeezed between two independent planar mirrors. We show strong modifications in the CARS forward and backward far-field radiation patterns. For low-order cavities, we demonstrate that most of the emitted power can be concentrated into

Coherent Anti-Stokes Raman scattering with reflective optics

Applied Optics, 1983
Attention is given to the implementation of a novel reflective optics configuration in which the lens normally employed for focusing and crossing the input laser beams in Coherent Anti-Stokes Raman spectroscopy (CARS) is replaced by a spherical mirror, allowing large crossing angles to be obtained with a single focusing device and permitting the laser ...

Polarization coherent anti-Stokes Raman scattering microscopy

Optics Letters, 2001
We report polarization coherent anti-Stokes Raman scattering (P-CARS) microscopy that allows vibrational imaging with high sensitivity and spectral selectivity. The nonresonant background signals from both Raman scatterers and the solvent are efficiently suppressed in P-CARS microscopy.

Broadband coherent anti-Stokes Raman scattering in silicon

Optics Letters, 2010
In silicon devices, the spectral bandwidth of coherent anti-Stokes Raman scattering (CARS) is limited by the narrowband nature of the Raman process in this medium. In this Letter, we report the observation of broadband wavelength conversion in silicon through CARS enhanced by the self-phase-modulation-induced spectral broadening of the optical pump ...

Quantum squeezing effects of radiation in stokes and anti-stokes modes in coherent anti-stokes Raman scattering and coherent anti-stokes hyper-Raman scattering

Journal of Modern Optics, 2004
The non-classical effects of squeezing of light in coherent anti-Stokes Raman scattering (CARS) and coherent anti-Stokes hyper-Raman scattering (CAHRS) are investigated under the short-time approximation based on a fully quantum mechanical approach. In an idealized model CARS, the interaction is looked upon as a process involving absorption of a pump ...
