System and method for polarization coherent anti-stokes Raman scattering microscopy |
摘要 |
Systems and methods are disclosed for detecting a nonlinear coherent field induced in a microscopic sample. The system includes in an embodiment, a first source for generating a first polarized electromagnetic field at a first frequency and a second source for generating a second polarized electromagnetic field at a second frequency that is different from the first frequency. The system further includes optics for combining the first polarized electromagnetic field and the second polarized electromagnetic field in a collinear fashion such that the difference in polarization angles is phi wherein phi is not equal to zero. The optics further direct the combined electromagnetic field toward a common focal volume. The system also includes a polarization sensitive detector for detecting a nonlinear coherent field that is generated responsive to the first and second polarized electromagnetic fields in the focal volume.
