Non-linear optics for molecular spectroscopy

Principal investigator : Julien Duboisset

Key words : Coherent anti-Stokes Raman scattering, spontaneous Raman, polarization, molecular order, vibrational modes.

We are particularly interested in investigate the molecular vibration for biological imaging and fundamental nonlinear spectroscopy. We develop method based on spontaneous Raman and coherent Raman scattering to directly image the symmetry of molecules in crystals and biological tissues, based on irreducible tensor formalism.

Since 2014, we are able to perform vibrational modes imaging in crystal, and assign their modes symmetry in single image acquisition. We are also able to perform molecular organization imaging in biological tissue and soft matter.
