DIFCARS: A versatile model of CARS signal generation
Description
Abstract A versatile model of coherent anti-Stokes Raman scattering (CARS) signal generation is presented. The model combines the novel treatment of CARS signal generation given by Teets with the realistic electric field distributions produced by the model of focused laser beams given by Evans and Grey-Morgan. The model provides a detailed picture of local contributions to the total CARS signal, including interference effects, as well as the total CARS power and the CARS spectrum. Illustrative applica... Title of program: DIFCARS Catalogue Id: ADAC_v1_0 Nature of problem The DIFCARS code calculates the distribution of coherent anti-Stokes Raman scattering (CARS) signal generation over the region of the overlap of the incident beams, the propagation of the incident beams being calculated at the diffraction-level. The calculation is performed in successive slices along and normal to the CARS signal's propagation axis, the slice contributions being summed in an appropriate manner to give the total CARS power.
