Synchronously scanned optical parametric oscillator (OPO) coherent anti-Stokes Raman spectroscopy (CARS) is a new technique that can be used with single-wavelength detection in order to reject background stray light and eliminate spectral interference. In this paper, results are presented illustrating the use of this method to also reject stray light from Rayleigh scattering without attenuation of the Raman signal, resulting in the ability to probe low-frequency Raman levels.
