Efficient heterodyne CARS measurement by combining spectral phase modulation with temporal delay technique.


We propose and demonstrate an improved heterodyne coherent anti-Stokes Raman scattering (CARS) measurement with a rapid phase modulation and temporal displacement of the background, to simplify signal extraction and effectively reduce a nonresonant background (NRB). This method is a modification of the single-beam CARS spectroscopy originally proposed by… (More)
