Coherent Anti-Stokes Raman Scattering (CARS)

Coherent Anti-Stokes Raman Scattering (CARS) is an advanced imaging technique that uses laser light to detect specific molecular vibrations within a sample. It involves firing multiple laser beams that interact with molecules, generating a new light signal at a different wavelength if the molecules match certain vibrational energies. This process produces highly detailed, label-free images of the sample’s chemical composition, making it valuable in fields like medical diagnostics and material analysis. CARS offers rapid, non-destructive insights into the molecular makeup of tissues or materials, providing high-resolution, specific information without the need for dyes or stains.
