Model for Predicting Relative Signal Power in Coherent Anti-Stokes Raman Spectroscopy.
Abstract
A more general mathematical model has been developed for the prediction of signal power generated by the Coherent Anti-Stokes Raman Scattering process (CARS). Like previous treatments the model assumes that the laser beams have Gaussian profiles. However, provision is made for varying a number of experimental parameters, either singly or in combinations. In particular, the model allows for non-collinearity of the laser beams, different beam diameters, lateral offset of the beam centers, and relative displacement of the focal points of the beams. Computational time requirements of the new model are not significantly greater than previous treatments of identical, collinear Gaussian beams, although the numerical integrations must be handled more carefully.
