We present a systematic characterization of coherent anti-Stokes Raman scattering (CARS) microscopy. CARS signal generation in a heterogeneous sample under a tight-focusing condition is formulated by the Green’s function method. The CARS radiation pattern and the forward- and backward-detected CARS signals from a three-dimensional Raman scatterer are calculated. The coherent nature of CARS image formation and its consequences for image contrast and spatial resolution are investigated. Experimental implementations of CARS microscopy with collinearly copropagating and counterpropagating excitation beams, forward and backward data collection, and polarization-sensitive detection are described. Finally, CARS images of unstained live cells with forward detection, epidetection, and polarization-sensitive detection are presented and compared.

  49. The most significant term for CARS radiation involving the z-polarized field is χzxxz(3) Epx Epx (Esz)*, which is ~1% of χxxxx(3) Epx Epx (Esx)* with χzxxz(3)xxxx(3) /3. Thus the radiation power from the former term is only 0.01% of that from the latter term. Moreover, the radiation from the former term is maximized in the z=0 plane, so little signal can be detected in the forward or the backward direction. Experimentally, we observed that the nonresonant CARS signal was highly polarized along the same direction as the parallel-polarized pump and Stokes beams. This observation verifies the validity of our assumption.

  59. As our calculation did not consider the contribution from the solvent surrounding the scatterer, the forward radiation pattern is a suitable description of polarization CARS for which the nonresonant background from the solvent is suppressed. The forward CARS generated by a pair of parallel-polarized pump and Stokes beams is a coherent addition of the signal from the scatterer and that from the solvent and is always highly directional.
