Abstract:
Methods of obtaining a multidimensional image of a sample are provided comprising (a) directing a first coherent light pulse having a first frequency ω1 and a first wave vector k1 at a first location in the sample, (b) directing a second coherent light pulse having a second frequency ω2 and a second wave vector k2 at the first location, (c) directing a third coherent light pulse having a third frequency ω3 and a third wave vector k3 at the first location and (d) detecting a coherent output signal having a fourth frequency ω4 and a fourth wave vector k4. At least two, but optionally all three, of the coherent light pulses each excite a different transition to a discrete quantum state (e.g., transitions to vibrational states or to electronic states) of a molecule or molecular functionality in the sample. Steps (a)-(d) are repeated at a sufficient number of other locations in the sample to provide the multidimensional image.
