Nonlinear-optical field cross-correlation techniques for medical imaging with lasers.
We show that certain resonant nonlinear-optical processes are capable of producing a cross-correlation function of the incident fields. This property can be used for time-gating purposes. Using a coherent anti-Stokes Raman scattering process as a time gate, we reproduce an image of an object obscured by a scattering medium.
