Paper Abstract
In this article we show that heterodyne CARS, based on a controlled and stable phase-preserving chain, can be
used to measure amplitude and phase information of molecular vibration modes. The technique is validated by
a comparison of the imaginary part of the heterodyne CARS spectrum to the spontaneous Raman spectrum of
polyethylene. The detection of the phase allows for rejection of the non-resonant background from the data. The
resulting improvement of the signal to noise ratio is shown by measurements on a sample containing lipid.
