Coherent Anti-Stokes Raman Spectroscopy

**Semantic type:** Laboratory Procedure

**Definition:** A nonlinear Raman spectroscopy technique. It uses two very strong collinear lasers to irradiate a sample, instead of the traditional single laser and is orders of magnitude stronger than spontaneous Raman emission.

**Synonyms:** - CARS - Coherent anti-Stokes Raman Scattering Spectroscopy
