Tutorial: Coherent Raman light matter interaction processes

Biological imaging with coherent Raman scattering microscopy: a tutorial.

Coherent Raman scattering (CRS) microscopy is gaining acceptance as a valuable addition to the imaging toolset of biological researchers. Optimal use of this label-free imaging technique benefits from a basic understanding of the physical principles and technical merits of the CRS microscope. This tutorial offers qualitative explanations of the principles behind CRS microscopy and provides info...

Interaction Matter-Polarized Light

This chapter presents the process of interaction of light, mainly in the xray range, with matter. The subject is introduced by some experimental evidences of x-ray absorption, emission or scattering by different kinds of material. The ways of describing the electromagnetic wave field are then briefly presented before developing its interaction with an electron in an atom. This process is then a...

Coherent control of light interaction with graphene.

We report the experimental observation of all-optical modulation of light in a graphene film. The graphene film is scanned across a standing wave formed by two counter-propagating laser beams in a Sagnac interferometer. Through a coherent absorption process the on-axis transmission is modulated with close to 80% efficiency. Furthermore, we observe modulation of the scattered energy by mapping t...

Coherent anti-Stokes Raman scattering imaging under ambient light.

We demonstrate an ambient light coherent anti-Stokes Raman scattering microscope that allows CARS imaging to be operated under environmental light for field use. The CARS signal is modulated at megahertz frequency and detected by a photodiode equipped with a lab-built resonant amplifier, then extracted through a lock-in amplifier. The filters in both the spectral domain and the frequency domain...
