    "abstract": "We present a new interferometric technique for measuring Coherent Anti-Stokes\nRaman Scattering (CARS) and Second Harmonic Generation (SHG) signals.\nHeterodyne detection is employed to increase the sensitivity in both CARS and\nSHG signal detection, which can also be extended to different coherent\nprocesses. The exploitation of the mentioned optical nonlinearities for\nmolecular contrast enhancement in Optical Coherence Tomography (OCT) is\npresented. Numerical simulations for both coherent nonlinear processes are\nperformed in order to determine the properties of the signal expected at the\nexit of the described nonlinear interferometer.",
