Coherent anti-Stokes Raman spectroscopy

{
  "id": "MLC-T-CHM-002179",
  "term": "Coherent anti-Stokes Raman spectroscopy",
  "field": "Chemistry",
  "definition": "A non-linear spectroscopic technique that generates a coherent anti-Stokes Raman signal by exciting molecular vibrations with two or more laser beams. The signal is produced at a frequency shifted from the pump beam by the vibrational frequency of the molecule. This method offers high spatial resolution and is used for label-free chemical imaging in biological samples.",
