Query: Direct imaging of molecular symmetry by coherent anti-Stokes Raman
  scattering   Nonlinear optical methods, such as coherent anti-Stokes Raman scattering
(CARS) and stimulated Raman scattering (SRS), are able to perform label free
imaging, with chemical bonds specificity. Here, we demonstrate that the use of
circularly polarized light allows to retrieve not only the chemical nature but
also the symmetry of the probed sample, in a single shot measurement. Our
symmetry-resolved scheme offers simple access to the local organization of
vibrational bonds and as a result provides enhanced image contrast for
anisotropic samples as well as an improved chemical selectivity. We quantify
the local organization of vibrational bonds on crystalline and biological
samples, thus providing new information not accessible by spontaneous Raman and
SRS techniques. This work stands for a novel symmetry-resolved contrast in
vibrational microscopy, with potential application in biological diagnostic.
